It may seem absurd to ask on an internet forum!
But the connectivity problems only seems to affect certain sites, and beaconcitizen.com is not affected.
The only news I could find on the issue is, of course, one of the sites that are not coming up. It is working on my cellphone, it only mentions Connecticut and Westchester:
It's not a DNS issue, DNS is resolving. Only certain sites don't respond, and the IP ranges seem random. The servers just don't respond.
Maybe it has to do with that backhoe that took out MetroNorth track signals yesterday in Yonkers and fouled the commute. Random guess, who knows.
