A graph demonstrating that the GitHub website's uptime suffered considerably after being acquired by Microsoft.
The graph shows average uptime of the website by-month from April 2016 to January 2026. Months that earn 100% are colored green, while months that miss that goal are colored either red or yellow, depending on some undisclosed metric of severity.
A line is marked in November 2018 where Microsoft acquired GitHub. Before that, no months were visibly worse than 100%. There's one red dot, but it's not visibly different otherwise. For the first year after the acquisition uptime is worse but acceptable, and stays above 99.95%: six out of 12 months earn 100%.
After October 2019 the story flips completely. Only one month has earned 100% uptime since then, and the remaining months vary wildly from 99.98% to about 99.70%. May 2023 was the worst, crashing almost as low as 99.5% uptime.
Honestly, it looks like a seismograph that's started recording an active earthquake.
