My web site is resolving to an IP address not listed by CloudFlare

DNS & Network
#1

I have started getting connection timed out errors (522) this morning and after investigating I have realized that my web site is now resolving to this IP address: 104.25.114.108. I have checked and while this is clearly a valid Cloudflare IP it doesn’t appear in the list of official IP addresses that I used to whitelist on my firewall: https://www.cloudflare.com/ips/

Has anyone else experienced the same behavior lately?

Thanks

It is part of 104.16.0.0/12

#3

You’re right, I didn’t realized that the bitmask was /12…

But that still doesn’t explain the timeouts I have been getting all morning!

#4

Thats a different question and if the address is blocked (not whitelisted) it naturally wont work.

#5

This address is already whitelisted (104.16.0.0/12), this is what I said in my first message!

#6

You said in your first message the address was blocked.

Anyhow, to answer your original question, no I didnt experience any such behaviour. You would need to provide more information for anything more concrete.

#7

Because I initially thought that 104.25.114.108 was a new one (not already whitelisted)!

Sorry for the confusion…

#8

Do you still get 522s? Whats the URL?

#9

Yes but the web site is only accessible from Canada so it probably won’t work for you…

#10

Can you post it nonetheless?

There you go: https://appia-dev.expretio.net/appia

The site actually does load for me
Also at http://sitemeer.com/#https://appia-dev.expretio.net/appia

You can forward the connection IDs of the 522s to support and maybe they can shed some light.
