I am a Hetzner customer. I was in the middle of migrating infrastructure from DigitalOcean to Hetzner, most of all because DO's i/o on their droplets has been abysmal for a long time now.

Hetzner's latest price increase doubled-to-tripled the costs of any new resources I would deploy there. I've now halted the migration and I am seriously considering going all the way back to colo.

This most recent price increase was not communicated months in advance. I'm kind of wondering if you're thinking of the other price increase that happened this year, and not the most recent one: https://news.ycombinator.com/item?id=48540844
