Background
I signed up with drupal value hosting in December 2007.

Initially, i was blown away by the performance their server's offered. I'm pleased to say that my feelings have not changed. I've since entirely cancelled my MediaTemple GridService account, and dropped down to a basic hosting package at 1and1 as my 'fall-back' in case DVH should have issues.

Their customer base has been rapidly increasing, but server performance and responsive support have not changed.

I've learned they don't offer FFMPEG, and was initially disappointed. However, I'm glad FFMPEG isn't offered, as the substantial server resources it requires could easily cause a noticable 'bad neighbor effect'.

I have 2 packages with them, the valuePrivateIP package, and the World's Best Hosting package.

Both seem equally snappy.

Soapbox
DVH really takes some heat over at the Drupal forums. People take jabs at the company because it's based in India and has no real track record. Some are concerned that they'll close their doors at any time and leave customers stranded.

I don't care where Amit (the guy who runs DVH) lives. His servers are fast, and they're split between Dallas and Seattle.

Could DVH shutdown their operations at any time? Sure they could. So could any other hosting company. It's a volatile business and you're kidding yourself if you think your sites are 'safe' with any webhost. You should always backup your data, no matter where it lives.

I always maintain at least 2 accounts across different hosting providers, just in case something happens to one. You could pick up a very basic hosting package at 1and1, or anHosting for around 5 bucks a month — a small price to pay for a fall-back plan.

I'll update again at 6 months with DVH.
