We have had a very similar experience, with two separate hostingrails
sites. We eventually moved all our sites over to railsplayground.net
and been happy with them so far.
I've never had a hosting company switch me to a new server without
thoroughly ensuring everything works and getting my approval before
throwing the switch. Hostingrails on the other hand, arrogantly just
moved my files over and sent me an email notification that my IP has
changed. Then all hell broke loose. SMTP failures, site down for hours
at a time, multiple times a day, tried to contact Support
continuously. The went on for over 2 weeks, as we moved to a new
hosting company. I have lost a major Beta customer in the process.
I was actually hung-up on by the "customer support" manager, Derek,
after I asked the support technician to transfer me to his boss,
because I dared to say the situation was "bullshit" ("I'm terminating
this call because of your bad language"). Support tickets are closed
without being resolved. Hostingrails used to have exceptional support.
Now its in the toilet.
In an attempt to give them one last chance, I tried to contact
"management" but there's none listed on their website. I called their
sales and support lines and asked for the name of the company
president, and was refused that information. Quite unbelievable.
