I switched to Tuta this morning. I used to be a huge Proton advocate but multiple hour-plus downtimes in a week for e-mail is unacceptable. At this point I had better uptime running my own mail server on a VPS (or at least when the UI went down it was a simple `systemctl restart` away to fix it) and this was in the dark ages of having to manually rotate X.509 certs.
