GitHub is once again down
GitHub is once again down
"It looks like you're trying to develop some software.

I wonder what the average career tenure of the userbase here is now, because Github was slow and flaky well before Microsoft got involved.
Maybe it wasn't as noticeable when Github had less features, but our CI runners and other automation using the API a decade ago always had weekly issues caused by Github being down/degraded.
An isolated group of customers are experiencing elevated error rates and degraded performance.
FTFY.
(I've read AWS word it like that)
MSFT acquired Skype in 2011, so I would say only a few months:

I remember seeing unicorn daily and "webhook delivery delayed" weekly. I think it got better, but also they got more traffic, now millions of agents read files separately over and over again.
IMO it's much better now.
The worst part of all this is that GitHub's CTO and VP of Engineering sent out the usual "here's what we'll do to fix things" letter to their larger customers and, without exaggeration, it boiled down to: 1) "Here's a bunch of stuff we already did!" which... clearly isn't working, and 2) "We're continuing our Azure migration." also clearly not working.
So needless to say, if you depend on GitHub for critical business operations, you need to start thinking about what a world without GitHub looks like for your business and start working your way toward that. I know my confidence in GitHub's engineering leadership is at rock bottom.
Even that doesn’t really make sense to me, unless they’ve done it in a way where everything has to move at once.
Everywhere I’ve worked, if a migration is causing this much downtime then you kill the migration or slow it down. If every change has a 10% chance of bringing the site down, you only do a change every week or two until you can work out the kinks.
Here are some relevant excerpts from an October 2025 article[1]:
> In a message to GitHub’s staff, CTO Vladimir Fedorov notes that GitHub is constrained on capacity in its Virginia data center. “It’s existential for us to keep up with the demands of AI and Copilot, which are changing how people use GitHub,” he writes.
> The plan, he writes, is for GitHub to completely move out of its own data centers in 24 months. “This means we have 18 months to execute (with a 6 month buffer),” Fedorov’s memo says. He acknowledges that since any migration of this scope will have to run in parallel on both the new and old infrastructure for at least six months, the team realistically needs to get this work done in the next 12 months.
If you consider that six month parallel window to have started from the time of the October memo (written presumably at the start of October), then that puts us currently or past the point where they would have cut off their old DC and defaulted to Azure only.
Whether plans or timelines changed, I have no idea of course but the above does make for a convenient timeline that would explain the recent instability. Of course, it could also just be symptomatic of increased AI usage generally and the same problems might have surfaced at a software level regardless of whether they were in a DC or on Azure.
Putting that nuance aside, personally I like the idea that Azure is simply a giant pile of shit operated by a corporation with no taste.

>It’s existential for us to keep up with the demands of AI and Copilot
if by chance the CTO reads this, as a user of GitHub I would find it really existential if GitHub continues functioning as a reliable hub for git workflows (hence the name), and I have the strong suspicion nobody except for the shareholders gives a lick about copilot or 'AI' if it makes the core service the site was designed for unusable
yeah currently working with Azure. what a PITA.
I wonder if the extended downtime is just due to the on-call engineers waiting for their azure auth tokens to refresh within azure's own damn network.
It's starting to really look like the AI effect. It might be coincidence but I've noticed a lot more downtime and bad software lately. The last Nvidia drivers gave me a blue screen (last week or so), and speaking about Windows, I froze updates last year because it was clear they were introducing a bunch of issues with every update (not to mention unwanted features).
I like AI but actually not for coding because code quality is correlated to how well you understand the underlying systems you're building on, and AI is not really reasoning on this level at all. It's clearly synthesizing training data and it's useful in limited ways.
GitHub has been unreliable since before AI. Though it's definitely gotten far worse.
Seemingly the decline started with the Microsoft acquisition in 2018, and subsequent "unlimited private repository" change in 2019 (to match Gitlab's popular offer)
Interesting how many people "Like AI" because it's good at all the jobs other than the one they happen to make a living doing.
Did you hear about the screenwriters school in which the professors said to avoid AI for writing, but it's great for storyboards. And the storyboard school where the professors said the opposite?
The reality is that AI isn't actually "good" at anything. It produces passable ersatz facsimiles of work that can fool those not skilled in the art. The second reality of AI is that everyone is busy cramming it into their products at the expense of what their products are actually useful for.
Once people realise (1), and stop doing (2), the tech industry has a chance of recovering.
