This just happened to me a couple minutes ago.
A client called complaining that his site was down. I checked and it said it "cannot connect to the database so I contacted the host." They told me that I had run out of database space.
Note however that there is no control panel form or any other way for me to monitor my available database space. Regardless, these people didnt even contact me they just shut down my client's site!!!
That's the last straw. After the hiddent fees, poor customer service, slow websites and now just plain disregard for my my business .... I AM LOOKING FOR A NEW HOST.
And this all started because when i wanted to find a reliable service I came to the home of DNN and clicked a webhost4life banner.
As the Official home of DNN you want a better reputation that recommending horrible service to the community. If I'm surer that you have had enough complaints if not please read http://www.dotnetnuke.com/tabid/702/Default.aspx.
Please work with them to improve their service or don't serve their banner.
