Hello, And hour ago all my sites routed through Cloudflare went down. Any help?
But Non cloudflare sites on the same server are working fine.
down mean? Is there an error code? If so what is it? Sample URL?
The site is timing out on connection and returns a 522 error.
I’d begin troubleshooting by reviewing:
It was working fine until like 2 hour ago.
does this looks like an attack?
Maybe? Cloudflare has a lot of graphs and screenshots these have no labels. It may be that your origin firewall or hosting provider saw a spike in requests and blocked Cloudflare IPs.
Once you’ve figured out why your origin is blocking requests you can review all of your logs / data and implement rules if/as needed.
