False 550 responses from Verizon

This week there was a reported uptick in user unknown responses for verizon email addresses. The specific response folks were seeing was:

Final migration of Verizon email addresses to AOL

AOL were kind enough to share some details about the shutdown of the Verizon mail system and the migration of @verizon.net email address to the AOL mail service:

Verizon changes but no time line

Yesterday there was a lot of talk about Verizon moving out of email and transitioning all their customers over to the AOL backend. The source was a page in the Verizon help center about transitioning an email address. There is no date on the page, so it’s unclear when this is going to happen or when it started.
I posted about Verizon beginning this transition back in May of 2016: Changes coming to Verizon email. The wording on the AOL page I link to is very similar to the wording on the page that was passed around yesterday.
Without a date it’s hard to really provide any advice, other than to maintain your list hygiene (you do have list hygiene programs, right?) and remove addresses that hard bounce. Quite honestly, I don’t think this will really have any effect on delivery. It doesn’t appear these changes are happening all at once, and Verizon customers have the option to keep their verizon.net address. They’re just going to have to access it differently.
For companies that use an email address as a primary key for logins or accounts, it’s probably a good time to contact customers with a verizon.net address and ask them to update their address. That’s a good idea most of the time, but when we know changes are happening at a domain level, it’s a requirement.

Changes coming to Verizon email

Last year Verizon bought AOL. As part of that merger some @verizon.net email is being migrated to the AOL backend. FAQs published by Verizon say this change is only affecting users in FL, TX and CA. Users will still have @verizon.net addresses but the backend and filtering will be managed by AOL.
This shouldn’t have a huge impact on commercial senders. However, one thing I did notice while reading through the FAQ is this:

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.
