If you can sign a did document (i.e. you've set up a recovery key), even if your old PDS refuses to cooperate (or disappears entirely) you can still move to a new PDS and deactivate your account on the old PDS (as this is done via your did document)[1]. It's not exactly trivial to do currently but tools are being developed that automate the process and render all this down into easy to use apps.
