Where did you keep the backup that you’ve taken this morning?

Do you still have access to your hosting control panel at all?

Are you sure your hosting provider closed down or did they close your particular account due to the malware?

Your website is loading fine on my end.

You may need to check with your hosting provider on whether your IP address is blocked by the server firewall.

That may explain why it is not loading for you without a VPN.

I agree with James that the best way to check this is to disable the plugins and re-enable them one by one.

You mentioned that this is intermittent. Does that mean that the CPU usage may or may not spike when you are editing a post?

One other possibility to consider is WP Cron. You may want to check if the CPU spike corresponds to the WP Cron.
