I wasted a bunch of time debugging the HTTP 500 errors on my site before I realized everything is 100% OK on my end, and that it's Cloudflare returning the error not my servers.
Ditto - I'm sitting here, wtf I'm not running Nginx on my blog, but I'm getting an Nginx response, hit IP directly....oooh.... right that doesn't make sense it's working fine. Cloudflare can't be down, that's next to, wait, status page (to their credit it's got a status note). HN here we go...
Would it be possible to adjust that 500 page to include an indication that it originates from Cloudflare, for the case that an outage like this happens again in the future?
