I bought a Textdrive VCII account earlier this year when my own servers were failing and I knew I needed a backup to fall back on if things went bad. Soon after my account was setup, I put a few new clients on my textdrive account and had them using pretty basic services. This was in early September, and things haven’t gotten any better.
It got to the point that I had to move these very basic level clients to a new hosting setup because Textdrive wasn’t even reliable for their email. We bought a PowerVPS machine in hold us over, but have been so happy with it that we probably won’t be moving for some time.
A simple google search for “textdrive sucks” will give you some background as to what is going on.
