Update:  As of about 16:00 UTC, the Bellsouth DNS server issue appears to have cleared.

We've received several reports telling us that Bellsouth.(net|com)'s services are down.  This seems to be not only affecting their DNS servers, but it also is affecting their Managed Services, email, hosted email, and who knows what else.

It does not appear to be affecting their managed internet services.

Thanks to the many readers who wrote in and let us know.
