I can't connect from Virginia on Comcast. I seem to recall a period a year or more ago when some "enhancement" on Comcast pervented us from connecting because "united.com" wasn't handled correctly by the Comcast DNS servers. Regretably, I've misplaced the direct ip address which worked back then (by bypassing the DNS lookup).

So, is there any commonailty with ISPs and failures to connect this morning?

Of course, during the last problem Comcast blamed United! (without merit based on my understanding of the underlying problem).
