I don't. The stuff I host on Scaleway is there because 1) I don't want to host it in the US, 2) an ARMv8 experiment, or 3) I need redundant bootstrap capacity in case GCE or AWS goes down.

The dynamic stuff I host for personal use uses a variety of cloud services as backends, and those are anycasted. One app I wrote in a hurry uses Google Sheets as a backend, and that's worked surprisingly well for the effort it took.
