US servers only DNS

Hello Everyone,

We just woke up today to find out our website was down, error 522. Investigated the servers and our entire setup and didn’t find any issues, noticed that error 522 was coming from CloudFlair servers is Hamburg and London so that when we found out the issue, we block outside of US access to our data center. Something happened last night to force all CloudFlare traffic through Europe now, is there a way to specify in our account to use only US based DNS servers?
