The problem is not at Fastmail, and it is not at your ISP (edge/connection) - the problem appears to me to be somewhere in the global interconnection of various networks/routing - This may be extremely difficult to solve. Already Fastmail down more than 12 hours. Definitely suggest trying a different internet connection - most people will have access to several - your cellphone mobile network, your wired/home network, your business network, a VPN may help. What I see from reverse traceroute (http://traceroute.org http://traceroute.org has huge list), there are many huge global network providers (Cogent, for example) that are unable to connect any edge point to fastmail servers. This is a massive global issue for Fastmail and I don't think they are handling it well.
