While on the phone with MS PPS - I asked (twice) him to consider the
PIX501 (while providing them full access to its logs and dashboard) as
the source of the problem. They consistently put that possibility to the
side (in reserve) and opted for the (disable EDNS) move. We'll find out
in the next 24 hours if he was right.
Side Note: When the cable guy came to run/install the co-axle cable, he
went into the attic and ran into a 5-foot black snake slithering between
the rafters.
