This was rumored to be a backhoe fade but the advisory refers only to
IP services and there was nothing in the popular press about any major
phone outage, so I have my suspicions.  Usually if there's a fiber cut
they say so.  About this time is when all of the major backbones began
flooding the net with their notices of panic upgrades.
