Is Fastmail Down?


I haven't been able to sync email for 75 minutes and cannot load the webpage. Other sites say it's up, though.

Both HTTPS and IMAPS work fine for me. HTTPS is also reachable from Qualys [1] and SecurityHeaders [2].

What IP's do you get when you look up www.fastmail.com? Does it match the DNS propagation checker? [3]

Here is the TLS fingerprint I get from port 25:

    openssl s_client -starttls smtp -crlf -connect in1-smtp.messagingengine.com:25 < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -in /dev/stdin
    SHA1 Fingerprint=6D:6E:C5:04:28:7D:10:3D:AD:FC:92:1B:84:64:7F:86:D3:05:87:27

I fixed it by hot swapping to another SIM then back. I will never understand what happened.
