As best as I can tell, there was less than 10 minutes from the last successful request I made and when the downtime was added to their status page - and I'm not particularly crazy with my usage or anything, the gap could have been less than that.
Honestly, that seems okay to me. Certainly better than what AWS usually does.
It appeared there like 5 minutes ago; it was down for at least 20 before that.
That's 20 minutes of millions of people visiting the status page, seeing green, and then spending that time resetting their context, looking at their system and network configs, etc.
It's not a huge deal, but for $200/month it'd be nice if, after the first two-thousand 500s went out (which I imagine is less than 10 seconds), the status page automatically went orange.
