    Many thanks to all those who replied. It did turn out to be a filter
    that needed updating at 7018, which was very quickly fixed by their
    team.

    :In short yes. AT&T uses a customer specific access list to perform a
    :uRPF like function. That is, if your provider did not request for
    :their provider to have AT&T update their filter.

    Indeed. We've used ATT MIS for many years and have been happy with
    their
    policies (which have blunted quite a few DDOS attacks), and their
    response
    to acl mod requests. They do tend to take longer than I'd like
    (on the order of several business days) for standard requests, though if
    you request expedition, response time is impressive.

    Overall, thumbs up.

    Yep. Always quite responsive. As with any other vendor, if you feel
    the
    person handling the call isn't qualified, escalate.
