I am also seeing a lot of 502 Bad Gateway errors as well as very slow responses. Our app is set to timeout after 7 seconds since when it's working well the responses are typically 100 - 300ms response times. So we are seeing a lot of timeouts after waiting 7 seconds as well. Today seems to be the worst it's been in a whle.

We are also experiencing slow response times and a lot of 502 - Bad Gateway errors this morning. Thy do seem to resolve these issues eventually.

I have been seeing the same Not Found results coming back inconsistently today. I have not noticed this many failures for some time so I am expecting that it is a temporary issue.
