Due to the AMS2 connectivity issues yesterday that affected all our droplets, a simple question came to mind (I just couldn’t find anyone posting this before).
We’re running a cluster with multiple failovers on loadbalancing, webserving and database level. That doesn’t help at all if ALL droplets in a datacenter have connectivity issues. Our monitoring that pings our servers every 10-30s is experiencing a lot of networking issues / small latencies that last no more than 10-20s, but mostly on all droplets at the same time. And of course yesterday it happened for 45 minutes. (Imagine furious customers now :-)).
Now, all our servers in AMS3 did’t have any issues. Therefore, is it possible for droplets to communicate with private networking enabled across local regions (AMS2 and AMS3)? We’re thinking about stretching our cluster across two regions, but we would need at least DB-Master/Master clusters to communicate across regions (over private networking).
