They're doing so as we speak. It takes a while to send 400,000 mails if you actually want them to be delivered to inboxes.

Agreed - especially having read this earlier (not being able to fix it at the time), still not getting the email (like 6 hours have gone by) and I'm resetting because I should and still no communication from Linode.

Concerning since I had to reset my password and regen my 2fa using only my old password...
