Pretty damning. Would also be interesting to see the number of commits overlayed. The graph tells a great story about the correlation with MS's takeover, but I wonder if at the same time that uptime went to shit, MS was shifting over large numbers of enterprise contracts to github. That would be a more complete story IMO.

None of which excuses this. Can you imagine someone's reaction in 2017 if you told them that github would be below 90% uptime in 2026? It would be unimaginable.
