Hi mate, it is a real pain in the butt to have to recover from this kind thing.
Before I started to build my node I spend a lot of time looking into the terms of these hosting companies and they all have the power to shut you down.
The best bet is to own your own server and host it in a reliable safe location, sure it more Short term pain but for a long term gain. Plus the decentration of hive witness nodes is important, this is a example on one hosting provider effecting several witnesses.
Then get another server as a backup so you can switch over if your primary has any issues. Nice to have for sure 😊 but a must for the top 20 in my opinion.
Anyway as you say its a good to to refocus your efforts, and I wish you a speedy resync.
PS. Thanks for your support for my witness, I am probably the only one running in Adelaide.
