If you check your control panel, you’ll see that your entry process usage in the last few days is like 5-10 times the set limit. I don’t know what you’re doing on that account, but it’s almost burning a hole in the server.
What you could do is to go to your domain name provider and remove our nameservers from your domain. This should prevent any new traffic from going to your site, which should keep your account online the next time it’s reactivated. After that, you can either set up IP address whitelisting or password protection on your site, and then switch your nameservers back.
This helps ensure that you can access the site and make improvements to reduce the entry process usage. Once you’ve implemented the optimizations, you can remove the IP filtering / password protection.
Entry process usage is generated by requests to PHP scripts on your website. So with your entry process usage, at least something is hitting your website quite hard. Unfortunately, we don’t record metrics detailed enough to tell exactly why that is.
If you don’t want to follow my suggestion, that’s fine. But it’s the only solution I can think of to let you access your website, except for upgrading to premium hosting of course. It’s your website and your call. But I wouldn’t be surprised if your website is quickly suspended again.
