#23This is the first DNS outage I've experienced with them in 3+ years, then again I host everything in their NY regions.

#24Yeah, tried to access our site and it was down. Really was expecting more out of Digital Ocean than to fuck up such an integral part of their infrastructure. In the future we'll be transitioning away from their DNS solution because this is unacceptable.
In the meantime, I'm going wait for post-mortem before deciding if I should continue using them for dns. Looking back over the status history, 1-2 incidents a year isn't that bad for my needs, but might be too much for you, which is fine (since I'm only hosting a couple of small side projects with them).

#25Does anyone know of a good strategy for DNS failover?
Well, there's a couple of strategies: - IP-diverse nameservers - TLD-diverse nameservers - BGP anycast IP-diverse nameservers requires that you expect that your DNS servers will go down rather than start returning bad results - I highly recommend having some sort of mechanism to hard-terminate access to those machines. TLD-diverse nameservers is just an extra strategy for reducing the risk that an upstream TLD issue…
Use multiple implementations, e.g. NSD/BIND for authoritative servers and Unbound/BIND for resolvers, to mitigate against implementation-specific bugs and vulnerabilities.

#26DNS is hard. Very hard. It may seems trivial when it works (hint: it's not), but some of the biggest fuck ups I've seen in my professional life were caused by strange DNS things happening or DNS servers going kaboom. I feel the pain of the DO engineers trying to mitigate this issue. I really do.
Me too. Just last week they had another problem with DNS on the client side of things: Resolving with the Google Public DNS, which most droplets use by default, didn't work reliably. I hope that they post a combined post mortem for both of those incidents.

#27We really need fail-overs in place...small team problems.
Re: DNS Outage at DigitalOcean
#28Their status page at https://status.digitalocean.com is also now giving an intermittent "500 Internal Server Error" nginx error, probably from the load. That's why you should use a service like https://www.statuspage.io for your important stuff, even though creating a status page is a fun side-project for a dev team.

So what you're saying is that instead of running their own Status Page on their own infrastructure that's reachable. They should outsource it to statuspage.io and pay another company to do it?
