At least they're being honest - I use Easyspace too - so far only ventured as far as mysql/php - found their support to be ok - bit rough on the edges sometimes as you experienced but efficient in terms of speed of response etc.
I like your site by the way....except that I too got the Jserv error -eventually.
I had a similar problem when I first set up my site 'cause Macromedia Dreamweaver MX wizards are set to open persistent connections to MySql - hence I quickly exceeded the max number of connections and an error code would be generated (can't remember which one). After a while the connections would time-out and it would work again, thus confounding the issue.
Changed a parm to make once-only connections and never saw the problem again. Is it possible that you are having a similar problem (*just guessing as I know zero about JServ/ASP*)?
