I've been with MDDHosting since January and found them through WHT. Prior to them I was with a budget site that was unreliable with constant downtime and extremely slow with the database and email.
MDDHosting's service has been excellent and top notice thus far. We love the speed of the site, the uptime, the support when needed (few and far between), and the features (the automatic backups are wonderful especially). There are so many avenues of support from your basic email and forums to AIM and Skype. Their email service is also quite good; using IMAP and setting it up on various clients Blackberry's they get their emails pushed to them via BIS (Blackberry Internet Services) in one minute or less.
As far as pricing is concerned it is quite fair; I even got a nice discount from them using a coupon found on WHT.
The only dockage of points would be for downtime during the day a few months ago when I personally used our web application we have hosted (understandable). This was an isolated incident that did not last very long and the impact was minimal. Michael the owner even replied to me via Skype right away. Since this incident (I believe in Feb. or March) it has been rock solid and as fast as ever.
The great thing about MDDHosting is that they are always looking to improve. In the short time I've been using them they upgraded there servers to use the latest and greatest SSD storage solutions and implemented a great automatic backup system.
Overall I would rate MDDHosting 9.7/10.
Sincerely,
