We feel the pain as well as our platform is unreachable. I'm now using an other DNS server and changed the nameserver in the domain-record. However the DNS propagation is taking some time. What are you doing at the moment as fail-over?

Sorry if I'm trying to "teach grandma to suck eggs" but can't you just enter the domain in your local hosts file. If it's a network that needs access then presumably you have some sort of proxy/cache that could be seeded with the necessary domain+IP pairing? I suppose these aren't possible if you're trying to demo on someone else's network or in a public space or such.
We just switched it over to Route53 and set up some fail-overs there. Took us 5 mins and we're back online.

Looks like DO is still offline so it seems to have been a good call...

You're back online from your perspective. What about all the name servers that have your SOA cached still looking at DO? You're still down for them.
Tough shit, lol. We now have reduced TTL times for future occurrences, but there's nothing we can do for those users who are still experiencing an outage.
Minimum TTL for SOA records on .com is a day. Lowering your A record TTL isn't buying you much in case of DNS hosting failure. Helpful if your site (not dns) needs to move providers though.
