Cloudflare International IPs

#1

We’ve whitelisted all the IPs at https://www.cloudflare.com/ips. However, we have an incident where a user is getting an Error 522. We noticed that the traffic is coming from Tokyo or Singapore (different retries). The source IP is Cloudflare’s. My question is, is there a list of IPs we need to allow other than the ones on the site mentioned above?

Thanks,

No, that should be it. Which IP was it?

That address is part of 172.64.0.0/13, which is listed on the page.

It turned out that we were missing a few CF networks. All is well.
