P1 call having to explain "what's an ip address" to their 'engineers'.
About 6 hours after we moved prod over, they brought down my EIPs for like 4 hours because of a route they didn't understand and flagged as spam, and in the end we rolled back the migration and cancelled the contracts.
Bummer for them; we ended up scaling out to several hundred thousand euro a year in OVH, which has been absolutely fucking exemplar.
So while some people really do rave about them, I was so annoyed by that experience that I will almost certainly never use them again.
Being a German myself, I'm 90% sure it's because the support is based in Germany, where technology goes to die.
