Question

Cross Region High Availability

Hello

On 04/22/20 there was a multi region outage with Digital ocean where NYC,SF and LO all had outages.

Since then I’ve been looking into how to setup multi region high availability and am not sure it can be done currently with Digital Ocean.

It seems like Load Balancers are locked to droplets in a single data center and Managed Databases servers are also locked to the same data center, even the backup standby nodes.

So my question is how do you setup your infrastructure in DigitalOcean so that you have redundancy setup across multiple regions?

Thanks!

Adding a reply to comment and follow this topic. I noticed that problem and from what I remember, pretty much all DO datacenters in the USA and some in Europe suffered from that outage at various degrees.

I took away from it that DO seems to be very reliant on a backbone bandwidth provider, and an outage at that provider took all these places down or at least created a whole lot of troubles – for what seemed to be a good part of the day, and became “all green” only the day after (that I saw).

@mindglitch , you might want to look at using DNS failover (or load-balancing). Many DNS providers (Route53, DNSME etc) do provide that functionality across regions or even providers.

Cloudflare or Fastly can do this at the HTTP-Proxy level, so you could add more intelligence than just a “healthcheck”.

As far as DO is concerned, they need to convince users that such an event “cannot” happen if you pick any two or even three DO datacenters. Unfortunately, that 4-22 event showed that it did happen.

As a customer, the only solution is to be ready to go with another provider. Myself, I use Linode as a no-DO failover (ongoing replication), but it would be more convenient to stay within DO, I agree.
