I was futzing around with the description for a PR and hitting save wouldn't update it, yet clicking edit would show the text I expected to see.
Suspecting something was up I checked Github Status but it was green across the board. Assuming enough other people hit the same chain of events, could it provide a reliable enough indicator of an issue?
Sure, the previous decent sized company (~1000+ devs) had that exact metric available.
Visits to the status page generally that is. Now whether you could actually correlate that to an increase in errors for a particular component, no so much ;)
I'm sure it's totally feasible but it requires a certain amount of discipline to have consistency in logging/metric standards across all your applications to some extent.
Even worse, some applications would return a shared error page but internally, I believe it was logged as a 301 redirect until someone spotted it :)

Yep, makes sense. I was picturing a broad "Something Bad Happened, Go Investigate" notification. But I imagine the sensitivity would have to be tuned, especially to account for massive traffic increases from places like HN.

Yikes!
