Does Fastmail actually have multiple providers?
One of their mail exchangers, web site, SMTP, POP, and IMAP servers are all on the same /24, that belongs to NYI (AS11403) and according to the BGP table is not multihomed.
Historical DNS records from last two years also show they weren't changed.
I guess, "primary" is still a technically correct qualifier for the "sole" provider.
- jjeaff 5y agoPerhaps their primary provider handles their SMTP traffic and any additional providers handle things like the cdn.
