Is anyone else having trouble sending emails with AWS SES, today?

[fofalaeixdeal]

All day, I've been having emails failing to send, with errors like:

I can't find posts by anyone else having issues, so I'm wondering if this is just me...

Some emails do send, but most are failing, all day today.

I've already looked into clearing DNS cache (in case that was it), upgrading the packages (I'm using Symfony Mailer SES Transport), and AWS CLI is up to date (although I'm not sure Symfony Mailer uses AWS CLI).
Is anyone else having trouble sending emails with AWS SES, today?
