I'm not a GitHub apologist, but that graph isn't at scale, at all. It's massively zoomed in, with a lower band of 99.5%. It makes it look far worse than it is.

It also has 0 reflection of load. Weren't you limited to a single private repo before Microsoft took over?

As long as they brand it as a part of GitHub by calling it "GitHub Copilot" and integrate it into the GitHub UI, I think it's fair game.

What is Google's uptime (including every single little thing with Google in the name)?

It depends, for example - I would consider Google Drive uptime as part of say Google Docs’ overall uptime because if I can’t access my stored documents or save a document I’ve been working on for the past 3 hours because Drive is down I would be very pissed and wouldn’t care if it’s Drive or Docs that is the problem underneath I still can’t use Google Docs as a service at that point.

> But if you take the point of view of a customer, it might not matter as much 'which' part is broken. To use a bad analogy, if my car is in the shop 10% of the time, it's not much comfort if each individual component is only broken 0.1% of the time. Not to go too out of my way to defend GH's uptime because it's obviously pretty patchy, but I think this is a bad analogy. Most customers won't have a hard reliability o…

Sorry, by 'customer' I meant to say something like a large corporate customer - you're buying the whole package, and across your org, you're likely to be a little affected by even minor outages of niche services. But yeah, totally agree that at the individual level, the observed reliability is between 90% and 99%, and probably toward the upper end of that range.

I’m grateful for GitHub and their support for open source, but they’re not getting any sympathy for the AI mess they’re generating (and they’re contributing more to the mess than many other organisations, due to their size, position and product strategy). They’re a big enough corporation that we can have nuanced feelings about them. Simultaneously grateful for one part of what they do, and unsympathetic for the conse…

true colors.

Mmm, you’ve shown yours too.

I got Claude to make me the exact same graph a few weeks ago! I had hypothesized that we'd see a sharp drop off, instead what I found (as this project also shows) is a rather messy average trend of outages that has been going on for some time. The graph being all nice before the Microsoft acquisition is a fun narrative, until you realize that some products (like actions, announced on October 16th, 2018) didn't exist…

It feels like they launched actions and it quickly turned out to be an operations and availability nightmare. Since then, they've been firefighting and now the problems have spread to previously stable things like issues and PRs

They rushed to launch Actions because GitLab launched them before.

BTW, GitLab called it "CI/CD" just as a navigation section on their dashboard, and that name spread outside as well, despite being weird. Weird names are easier to remember and associate with specific meaning, instead of generic characterless "Actions".

I don't think so. Even before Microsoft acquired GitHub, you could have as many private repos as you wanted, but you couldn't have more than 3 collaborators. This change happened back in 2019:

It’s biaised to show this without the dates at which features were introduced. A lot of the downtimes in the breakdown are GitHub Actions, which launched in August 2019; so yeah what a surprise there was no Actions downtime before because Actions didn’t exist.

Even worse, those features show "100% uptime" pre-existence on the breakdowns page too.

This is the real questionable part of the graphic. It seems that no-data pre 2018 was just considered 100% uptime (which is hardly historically accurate).

I'd like to move off GitHub, and I deploy some websites using GitHub Pages, so I took a look at the availability of static web hosting; GH actually does really well on this metric, although Fastly, the CDN they use, should get the credit.
