5XX error from Canadian Edge Systems

Performance
#1

For over a week now we have been having “spikes” of 5XX errors from the following Canadian Edge Servers:

on the following Canadian Edge Data Centers:

Winnipeg, Canada (YWG)
Ottawa, Canada (YOW)
Toronto, Canada (YYZ)

Sometimes 50% of the transactions monitored in Analytics are ended in this manor.

I opened at ticked about 5 hours ago with the Support team, but as yet, no response. (yes, i nudged the ticket to try to get around the BOT). Ticket #2337141 - 520 and 525 Status Codes for YWG YOW and YYZ (other CF Datacenters not affected) Why?

Analytics information posted in the ticket.

Any idea why this would be happening?

#2

I’d noticed that myself with mine, primarily, through YYZ off-and-on for about a week. That was a week ago. I’ve not noticed it lately though.

Do you have direct access through a Canadian Edge? The edge centers we are having the most trouble with are:

Ottawa, Canada (YOW) - 230
Winnipeg, Canada (YWG) - 198
Toronto, Canada (YYZ) - 141

status 520 and status 525 error count in the last 30 minutes (according to analytics… roughly 25% of the actual transaction attempts).

Edge Centers in the North America(Except Canada), South America, Europe, Africa, Asia, Middle East, and Oceana are not having this issue at all.

I’m in near-northern Ontario. As mentioned, I’ve noticed it with my zone through YYZ recently. While I’ve not noticed the 5xx errors for at least a few days, I was seeing them off-and-on for around about a week or so.

Are your Origin Servers based in Canada? Or elsewhere?

I suspect it may have something to do with traversing multiple paths to get from Cloudflare edge to the Origin.

#6

My origin servers are, primarily, in the US. While I do have stuff in Canada, the one I was noticing the 5xx errors with is in the US.
