There can only be so many "I saved 10x by moving to Hetzner" posts before they pick up the value they were leaving on the table...
The same will happen with the other providers.
Hetzner just achieved their pricing by using commodity consumer hardware.
This is now making them the canary, as they don't have the multi year business contacts the others have - so they're uniquely vulnerable to the current consumer hardware price increase.
But the rest will follow, unless the bubble burst, which is unlikely to happen before the others increase their costs, too
I moved to Scaleway one or two price upgrades ago. Be ready to see the same, but with OVH or Scaleway instead.
Just wait for the hyperscalers to follow suit
