Hi, I believe I'm seeing intermittent issues in comcast's SFBay area network,
at or near..

te0-3-0-5-ar01.oakland.ca.sfba.comcast.net (68.87.192.34)
te-9-1-ur02.sanmateo.ca.sfba.comcast.net (68.87.192.18)
GE-1-3-ur01.sanmateo.ca.sfba.comcast.net (68.86.90.137)

..from two perspective of two different net locations. If you want you can
contact me at this address off list.

HTH & thanks,
