Your account is suspended for High Server Usage, specifically using 200.38 GB memory when the limit is 200 GB.
Node is one of the top reasons for users getting their accounts suspended, since it uses a lot of server resources. We have a Node.js guidance page in the Wiki here: https://wiki.helionet.org/Node.js and if you use Node, we recommend you structure your app in the same way as the example app in the tutorial. Following this structure will make sure your Node app uses Passenger, to help try to keep the load within the limits allowed on the shared hosting server.
I have unsuspended the account now. Please fix the issue quickly or else the same high load is likely to happen, which will lead to the system suspending your account again and there are a limited number of unsuspensions that can take place for the same reason.
