A much bigger entity, but I know the European Bank has 2 datacenters (Amsterdam and Rome), connected by 2 separate backbones going through completely separate geographic areas and they switch from one datacenter to another every 6 months to test out their DR. In fact, they have been doing that for decades.
- vlovich123 4y agoWhy switch 100% instead of continuously running both with transparent failover in case of failure? It seems like you risk a major outage every 6 months with the current scheme unless I’m missing something.
- jbverschoor 4y agoBecause of the same reasons we do continuous integration.
- aledalgrande 4y agoIt was told me years ago, so I'm not sure of the details. What they are doing is probably switching the traffic to the main DC, not switching off completely one.
