Congestion at Verizon
Yahoo! finally found their broken cable (I had no idea Yahoo had fiber) and fixed it. Now, I’m seeing a lot of reports that Verizon is accepting mail very, very slowly. Some folks are reporting no more than 20 messages a minute. This could be due to congestion, and just an underpowered system, or it could be some purposeful throttling on Verizon’s end.
In any case, this is affecting a lot of senders and not just the marketing end of things.
Updates as I get them.
