We emailed you a couple of days ago that your site will be down for some time as we are migrating to new more powerful servers.
You are now on 24GB RAM Dual Xeon Quad codes (8 cores/8threads) processors with RAID and the latest Centos and Perl 5.18.1 and the latest software like MySQL etc.
We are still now in the migration and tuning process.
Your site now is working normal as I check it yesterday after it migrated.
