I have had a couple of serious downtime incidents in the last year or two. The last one was almost two days, and I do not clearly recall the first one but I believe it was more then one day and was perhaps more forgivable because it was caused by a catastrophic total power failure in their data center.
However, this last incident was just (as far as I am aware) my little server, and it took them more then ten hours to even acknowledge my trouble ticket. And a total of more then forty hours to get the server running again. That is just unacceptable, even on the weekend.
I believe that in the past they were faster in responding to trouble tickets. Maybe it has something to do with a change in management, I do not know. Under the circumstances, they agreed to cancel my account without penalty and this week I moved my server to Rackspace.
As of September 2009 I have been running a VPS Xen server on vpslink for just over a year now, and am sufficiently satisfied with their service to start giving them six months of money at a time and increase my server to 128M so I can also run Apache. So I am now running a lightly loaded e-mail server and a web server on my vpslink VPS.
There have been some issues with uptime in the past year, but their tech support has always been prompt in addressing outages, and generally I believe them to be a good company to work with.
Just for the record, I bumped into another ISP that challenges their low price-point with a 512M OpenVZ VPS for only $6 per month. (I believe that OpenVZ means no swap.....) If this is not a temporary teaser price, they might be worth checking out at some point.
As of summer 2008, I have been using a vpslink.com VPS for a about a month now, and so far, all is well, especially the price.
If your needs are simple, their 64 MB RAM / $7.95 plan is a good deal. If you choose XEN hosting, you also get some swap. I currently have postfix / dovecot / MySQL and a couple other minor daemons running in this skinny little RAM no problem, no swapping (and as yet, very little load! I am still setting up....)
There is a wide choice of Linux distros to choose from for your VPS, I chose Debian.
This is my first VPS, so I can't really compare with other service offerings. I can say that getting installed and setup was trivial, and thereafter everything works just like the same old Debian I am used to.
The only snafu so far is some unnecessary password confusion. When you start up with the service, the same password works everywhere. However, if you start changing passwords, you will soon find that your newly changed password does not necessarily apply everywhere you think it should. And most confusing of all, at least the first time, if you reboot your server from the Control Panel on their website, the root password gets reset to the original password. Lesson: keep that original password safe, you might need it for a long time.
I will keep this post up-to-date with my on-going experience.
