Drupal Hosting, Any good hosts?

I recommend https://www.nearlyfreespeech.net/, they've been fast, reliable and extremely cheap (only pay for what you use, which is perfect since I have lots of small sites).

You can see how they perform on my site http://www.irrow.com/, please note that the site is work in progress, and its still quite small.

I strongly recommend against using Siteground. Our experience with them has been nothing but problematic, and we're in the process of leaving them. We started out with a shared hosting account prepaid for two years, and a few months later when our traffic required more we upgraded to a VPS. But they won't refund the prepaid portion, nor have they applied it to our current bill. The upgrade also caused file permissions on most folders on our account to keep resetting to a very restrictive access level, which frequently locks down important parts of our site. They also scaled back their help desk right after we joined, so that you can only ask questions based on a handful of very specific scenarios. They have no chat support and no phone support.

We've also had trouble with renewal--they won't allow us to set up a monthly auto-renewal for the VPS account, requiring us instead to log-in to renew manually each month. But the renew button is missing from our account page! So for the past few months we've had to let the account become suspended before they'll acknowledge the problem and send us a (one-time) link for renewing. But they never fix or even acknowledge the underlying problem with the broken account page.

At best, they're just incompetent. At worst, they're unethical.

We used BlueHost in the past, and we should never have left them.
