I host my website FactoftheDay.CA on Heliohost.  The experience has been very satisfactory, with a few outages of significant length but on the whole quite good.  Today I went to check the site and it says "Account Suspended".  There's no illegal content, so the reason for suspension must be that I didn't log into cPanel for a month or that one of the wordpress plugins went crazy and used too many resources.  Note:  The only plugins I use which might have been a problem are WP-Supercache (which generates html files from php) and XML-Sitemap generator (which makes a single xml sitemap).  Neither should have hogged too much processing power or memory.  I have also clicked the "reactivate" link and logged into cPanel.   
Assuming the problem was inactivity- how long does it take for the site to come back after reactivating and logging into cPanel? 
Assuming the problem was system resources- what process is there for me to find out what caused the problem and log in to wordpress to fix it?   
My cPanel account is factday.   
PS- cPanel says I have used 0/2500 MB of Monthly Bandwidth Transfer, which seems impossibly low.  The last three months have been between 400-1000MB.
