This is configuring aliases (both Fastmail aliases and your own domain aliases) to deliver mail to a backup account at an unaffected backup mail provider as well as Fastmail. Because of the way Fastmail's MX servers are distributed and configured, this allows the backup mail service to receive email even when delivery to Fastmail's main data centre is not possible (and where you cannot access the messages if they are delivered). In my case, the backup mail service is not as convenient to use, mostly because I only use it in an emergency, and the messages (new and old) are not properly organised. However, it does mean I can always access urgent messages during events such as the latest DDoS attack.
I was also able to use my backup email provider, with all my Fastmail email coming into the backup email just fine.
I was surprised (happily) that the DDOS attack didn't affect the forwarding to the backup provider.
So I'm glad about that "MX servers are distributed ...." thingy that you describe above.
Worked for me.
