... This site and this directory were driving up server load averages, which causes instability for all users on this server. Our block on this site appears to have blocked over 150,000 connections in about half an hour. This is simply more than is appropriate for a shared server.
You may want to review your domain's traffic logs to see what kind of traffic this site is getting. The logs for today will be distributed at midnight EST tonight. If the traffic to this site is legitimate, you should look into a dedicated or a virtual private server. If the traffic is not legitimate, you should block it. I can provide assistance with that if you need it.
This domain and this directory will need to be disabled until traffic dies down, traffic is blocked, or your account is upgraded from shared hosting. If you need access to the directory so that you can make any necessary changes, please let me know.
