    We've migrated our WHM/CPanel server over to a new set of IP's and for some reason I can't connect to them without using a public proxy, this even includes the providers website now. I can't figure out exactly who is responsible and where the point of failure is exactly to get whoever is responsible to fix it......

    Traceroute/ping from my home location to the old server (which works)...

    Looks like you are passing through a netsplit condition out on the open internet
    in route to your final destination and it would appear that the problem point
    is a gateway between AT&T's network and Global Crossing's network.

    There is probably very little you can do other than just sit and wait because
    based on the information you posted, I would say there is nothing wrong
    with either your server or your ISP.

    The problem is out on the open internet between those two destinations and
    you are just passing through a bad part of the internet. This can have the
    effect of making your destination address appear down or slow to you even
    though it may actually be fully online and working fast in reality.

    Think of it as trying to drive your car from New York to Los Angeles and
    when you get to Tennessee, the roads are all ripped up with road
    construction so you are stuck in traffic waiting to get through Tennessee
    and it takes you a much longer time to get to Los Angeles even though
    things may be running good both at your final destination and also
    the place where you started.

    These sort of things usually clear up on their own in a few days fortunately.
    If not, you can contact AT&T and Global Crossing and put on some pressure
    but that usually does not accomplish much as there are probably another
    million people out there already calling them on the same issue.
