I tried to warn them that they were hosting a phishing site once and they weren't very receptive.

Otherwise, I hosted a site with them for years and all went well.

A warning sign indeed for long time users of DO. Their marketing basically says "yes, we handle those".

They're also too stupid to understand that they've been dropping UDP datagrams with src port == dst port and < 1024. This obviously breaks IPsec IKE. I showed them dummy traffic captured with netcat and tcpdump, but they refused to admit they caused the problem. They repeatedly claimed to see nothing dropped between the pcap files, that I was doing it to myself with a firewall that wasn't even enabled, or that this is just how a network is supposed to work.

I migrated a client off for the same reason. The “app platform” ran behind Cloudflare, but they run the Cloudflare, so I couldn’t put it behind my own Cloudflare, nor could I configure it and solve the problem. Moved the entire thing to Hetzner, fast. What a week.
