GitHub Uptime and Microsoft

Recently GitHub reliability has been getting worse. It’s 2020 July 13, Monday and GitHub wasn’t working for around 2 hours. Take a look at their status page. You’ll see something like the screenshot below, taken at 2020-07-13 07:33 UTC.

GitHub Status on 2020-07-13

Millions of individuals and businesses rely on GitHub daily. Having that in mind, I am surprised how GitHub allows such a generous error budget for themselves. For example in April 2020 it went down to 99.67%.

After exploring their historic status page data I noticed one interesting pattern. GitHub started having uptime issues around November 2018. Only a month after Microsoft announced their acquisition was complete. Whether it’s coincidence or consequence, you decide.

Take a look at historic uptime for Git Operations.

It’s not only Git Operations, but other services too. Explore their uptime page and you’ll see similar pattern. API Requests, Web-hooks, Issues, Pull Requests, Projects were having downtimes even more often than Git Operations.

Let’s hope it’s temporary and GitHub error 500 won’t become their own version of Blue Screen of Death. In this case it would be Green Screen of Death (GSoD or GhSoD).
