500 Errors from YYC datacenter between 3:15 and 3:35pm PT today?

We use workers quite heavily and randomly today, for about 15-20 minutes, we were getting 500 Internal Server Errors on our domain, but only for those who were routed through the YYC datacenter. Did anyone else experience something similar?

Cloudflare support basically told us to contact our hosting company because Cloudflare doesn’t throw 500 errors, which confuses me because I’m fairly sure Cloudflare hosts workers.
