While GitHub obsess over shoving AI into everything, the rest of the platform is genuinely crumbling and its security flaws are being abused to cause massive damage.
Last week Aqua Security was breached and a few repositories it owns were infected. The threat actors abused widespread use of mutable references in GitHub Actions, which the community has been screaming about for years, to infect potentially thousands of CI runs. They also abused an issue GitHub has acknowledged but refused to fix that allows smuggling malicious Action references into workflows that look harmless.
GHA can’t even be called Swiss cheese anymore, it’s so much worse than that. Major overhauls are needed. The best we’ve got is Immutable Releases which are opt in on a per-repository basis.
I worry that CI just got overcomplicated by default when providers started rocking up with templated YAML and various abstractions over it to add dynamic behaviour, dependencies, and so on.
Perhaps mixing the CI with the CD made that worse because usually deployment and delivery has complexities of its own. Back in the day you'd probably use Jenkins for the delivery piece, and the E2E nightlies, and use something more lightweight for running your tests and linters.
For that part I feel like all you need, really, is to be able to run a suite of well structured shell scripts. Maybe if you're in git you follow its hooks convention to execute scripts in a directory named after the repo event or something. Forget about creating reusable 'actions' which depend on running untrusted code.
Provide some baked in utilities to help with reporting status, caching, saving junit files and what have you.
The only thing that remains is setting up a base image with all your tooling in it. Docker does that, and is probably the only bit where you'd have to accept relying on untrusted third parties, unless you can scan them and store your own cached version of it.
I make it sound simpler than it is but for some reason we accepted distributed YAML-based balls of mud for the system that is critical to deploying our code, that has unsupervised access to almost everything. And people are now hooking AI agents into it.
I'm trying out SelfCI [1] for one of my projects and it's similar to what you were describing. My whole CI pipeline is just a shell script that runs the actual build and test commands, I can write a script in another language like python if I need more complexity and I can run it all locally at any time to debug.
From GitHub CTO in 2025 when they announced they're moving everything to Azure instead of letting GitHub's infrastructure remain independent:
> For us, availability is job #1, and this migration ensures GitHub remains the fast, reliable platform developers depend on
That went about as well as everyone thought back then.
Does anyone else remember back in ~2014-2015 sometime, when half the community was screaming at GitHub to "please be faster at adding more features"? I wish we could get back to platforms (or OSes for that matter) focusing in reliability and stability. Seems those days are long gone.
This was before Actions and a whole lot of other non-git related stuff. There was years (maybe even a decade?) where GitHub essentially was unchanged besides fixes and small incremental improvements, long time ago :)
> I wish we could get back to platforms (or OSes for that matter) focusing in reliability and stability
That's only a valid sentiment if you only use the big players. Both of those have medium/smaller competitors that have shown (for decades) that they are extremely boring, therefore stable.
Try convincing the CTO that this panoply of smaller players will be around for 5yrs or worth the effort migrating to.
I'm at a much smaller outfit now so we have more freedom but I'd dread to think the arguments I would've had at the 4000+ employee companies I was at before.
Have anyone checked out the status page? It's actually way worse than I thought, I believe this is the first time I am actually witnessing a status page with truly horrible results.
And notably, that page makes this post's title inaccurate. As of this morning, it says `90.21% uptime`, which is a _single_ 9, not 3 (though that's for the platform as a whole, no individual component appears to achieve three 9s.)
This is ... surprisingly honest? The one above is "missing" status page; and most status pages would legally have to be filed in the "fiction" section of the library.
Just to add a little bit of nuance to this not because I'm trying to defend GitHub, they definitely need to up their reliability, but the 90% uptime figure represents every single service that GitHub offers being online 90% of the time. You don't need every single service to be online in order to use GitHub. For example, I don't use Copilot myself and it's seen a 96.47% uptime, the worst of the services which are tracked.
On the other hand: it also doesn't include instances where GitHub is painfully slow but technically usable.
These days it is very common that something like opening the diff view of a trivial PR takes 15-30 seconds to load. Sure, it will eventually load after a long wait or an F5, but it is still negatively impacting my productivity.
I only use GitHub (and actions) for personal open-source projects, so I can't really complain because I'm getting everything for free¹. But even for those projects I recently had to (partially) switch actions to a paid solution² because GitHub's runners were randomly getting stuck for no discernible reason.
wait they still have 3 ninth, it really doesn't feel like that
but then their status center isn't really trust-able anymore and
a lot of temporary issues I have been running into seem to be temporary,
partial, localized failures which sometimes fall under temp. slow to a
point of usability. Temporary served outdated (by >30min) main/head. etc.
I’m surprised it’s even as high as three nines, at one point in 2025 it was below 90%; not even a single nine.[0] (which, to be fair includes co-pilot, which is the worst of availabilities).
People on lobsters a month ago were congratulating Github on achieving a single nine of uptime.[1]
I make jokes about putting all our eggs in one basket under the guise of “nobody got fired for buying x; but there are sure a lot of unemployed people”- but I think there’s an insidious conversation that always used to erupt:
“Hey, take it easy on them, it’s super hard to do ops at this scale”.
Which lands hard on my ears when the normal argument in favour of centralising everything is that “you can’t hope to run things as good as they do, since there’s economies of scale”.
These two things can’t be true simultaneously.. this is the evidence.
Windows (including Notepad and Explorer), too. I think ~Office~ ~Office 365~ ~Microsoft 365~ Copilot 365 is still technically useful despite the insane branding and licensing and AI slop features, but I doubt it'll last much longer.
Think the world would be a better place if 70-80% uptime were more tolerated. We really don’t need everything available all the time. More time to talk to each other, to think, more “slow time”.
I wonder how much of this is down to the massive amount of new repos and commits (of good or bad quality!) from the coding agents. I believe that the App Store is struggling to keep up with (mostly manual tbf) app reviews now, with sharp increases in review times.
I find it hard to believe that an Azure migration would be that detrimental to performance, especially with no doubt "unlimited credit" to play with?
You can provision Linux machines easily on Azure and... that's all you need? Or is the thinking that without bare metal NVMe mySQL it can't cope (which is a bit of a different problem tbf).
A migration like this is a monumental undertaking to the level of where the only sensible way to do a migration like this is probably to not do it. I fully expect even worse reliability over the next few years before it'll get better.
I'm amazed Microslop let us keep GitHub this long. Probably because they're training AI on it? To have a direct line to developers? I don't see why else they would've bothered with something that was so anti everything they stood for
I'm surprised GitHub got by acting fairly independently inside Microsoft for so long. I'm also surprised GitHub employees expected that to last
The real problem today IMO is that Microsoft waited so long to drop the charade that they now felt like they had to rip the bandaid. From what I've heard the transition hasn't gone very smoothly at all, and they've mostly been given tight deadlines with little to no help from Microsoft counterparts.
why is az devops on the floor? i am having to choose between the clients existing az dops and our internal gitlab for where to host a pipeline, and i don't know what would be good at all
It works fine,it just feels like it has been under a kind of maintenance mode for a while.
There's clearly one small team that works on it. There are pros and cons to that.
It hasn't even got an obnoxious Copilot button yet for example, but on the other hand it was only relatively recently you could properly edit comments in markdown.
If the client has existing AzDo Pipelines then I'd suggest keeping them there.
This was after seeing those ridiculous PRs where microsoft engineers patiently deconstructed AI slop PRs they were forced to deal with on the open source repos they maintained.
When he was gone a few months later and github was folded into microsoft's org chart the writing was firmly on the wall.
He was never truly independent though. The org structure was such that the GitHub CEO reported up through a Microsoft VP and Satya. He was never really a CEO after the acquisition, it was in name only.
Also of note is that the Microsoft org chart always showed GitHub in that structure while the org chart available to GitHub stopped at their CEO. Its not that they were finally rolled into Microsoft's org chart so much as they lifted the veil and stopped pretending.
I never said he was "truly independent" nor meant to imply it.
Nonetheless it looks like he was both willing and able to push back on a good deal of the AI stupidity raining down from above and then he was removed and then, well, this...
I worked on the react team while at GitHub and you could easily tell which pages rendered with react vs which were still using turbo. I wish we took perf more seriously as a culture there
To me, Github has always seemed well positioned to be a one-stop solution for software development: code, CI/CD, documentation, ticket tracking, project management etc. Could anyone explain where they failed? I keep hearing that Github is terrible
It always starts out good enough, but the reason they pursue horizontal integration is that it ensures that you won't be able to get out even if (when) you eventually want to. You'll be as glued as a fly to flypaper.
That's the reason you hear the complaints: they're from people who no longer want to be using this product but have no choice.
Because Microsoft doesn't need to innovate or even provide good service to keep the flies glued, they do what they've been doing: focus all their resources on making the glue stickier rather than focusing on making people want to stay even if they had an option to leave.
We use GH and are investing more in the platform features.
Codespaces specifically is quite good for agent heavy teams. Launch a full stack runtime for PRs that are agent owned.
> keep hearing that Github is terrible
I do not doubt people are having issues and I'm sure there have been outages and problems, but none that have affected my work for weeks.
GH is many things to many teams and my sense is that some parts of it are currently less stable than others. But the overall package is still quite good and delivers a lot of value, IMO.
There is a bit of an echo chamber effect with GH to some degree.
As of recently (workflows worked for months) I even have part of my CI on actions that fails with [0]
2026-02-27T10:11:51.1425380Z ##[error]The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled.
2026-02-27T10:11:56.2331271Z ##[error]The operation was canceled.
I had to disable the workflows.
GitHub support response has been
“ We recommend reviewing the specific job step this occurs at to identify any areas where you can lessen parallel operations and CPU/memory consumption at one time.”
That plus other various issues makes me start to think about alternatives, and it would have never occurred to me one year back.
We've jumped ship to self-hosted Jenkins. Woodpecker CI looks cool but Jenkins seemed like a safer bet for us. It's been well worth the effort and it's simplified and sped up our CI massively.
Once we got the email that they were going to charge for self-hosted runners that was the final nail in the coffin for us. They walked it back but we've lost faith entirely in the platform and vision.
"Agreed on the echo chamber point. For solo indie projects the overhead of GH Actions adds up though — I moved to self-hosted deploys and cut the complexity significantly. Different tradeoffs for teams vs solo."
Ever since Microsoft's acquisition of GitHub 8 years ago, GitHub has completely enshittified and has become so unreliable, that even self-hosting a Git repository or self-hosted actions yourself would have a far better uptime than GitHub.
This sounded crazy in 2020 when I said that in [0]. Now it doesn't in 2026 and many have realized how unreliable GitHub has become.
If there was a prediction market on the next time GitHub would have at least one major outage per week, you would be making a lot of money since it appears that AI chatbots such as Tay.ai, Zoe and Copilot are somewhat in charge of wrecking the platform.
Any other platform wouldn't tolerate such outages.
Anyone who used the phrase "measly" in relation to three nines is inadvertently admitting their lack of knowledge in massive systems. 99.9 and 99.95 is the target for some of the most common systems you use all day and is by no means easy to achieve. Even just relying on a couple regional AWS services will put your CEILING at three nines. It's even more embarrassing when people post that one GH uptime tracker that combines many services into 1 single number as if that means anything useful.
Three 9s is a perfectly reasonable bar to expect for services you depend on. Without GitHub my company cannot deploy code. There is no alternative method to patch prod. In addition many development activities are halted, wasting labor costs.
We wouldn’t couple so much if we knew reliability would be this low. It will influence future decisions.
GHA can’t even be called Swiss cheese anymore, it’s so much worse than that. Major overhauls are needed. The best we’ve got is Immutable Releases which are opt in on a per-repository basis.
