    Exclamation URGENT: None of my servers can resolve outside using XO

    I'm not sure when this started but none of my servers can run a WHOIS. They all state:

    Unable to connect to remote host

    I can use nslookup but certain services require hostname look up. I can ping outside. I have already power cycled my external firewall with no change.

    I don't know what to check. Could this be an XO issue since my nameservers go through theirs? ALL of my servers cannot have an issue at one time.

    Yes it could be an issue with your resolvers.

    You could get your provider to look into it or hire a management company.

    I presume your on linux ? perhaps change your resolvers in /etc/resolv.conf

    I AM THE PROVIDER and my servers have been provisioned for years and working correctly. I ahve even changed the nameservers used for lookups. I have over 100 servers that suddenly cannot do an outide lookup of a URL or IP.

    Well that is the most likely reason.

    Could be a hardware issue but unlikely, check with your datacentre for network issues.

    It's not possible to diagnose a server issue on a forum.

    It is not 1 server but over 100. Not a hardware issue on my end. And yes, problems are resolved through forums all the time

    Presumably no one is having any issue connecting to the server, it's just the server can't ping or access outside urls ?

    Contact your network provider for that many servers it's almost definitely that.
