Glad to hear it.

VPSLink is now offering Xen?  That makes a difference.

When I was using them, they just had the OpenVZ service.  They used to 
set up the boxes with no swap, and adding swap wasn't allowed.  As a 
result, you'd run out of memory a lot more easily, and see random stuff 
fall prey to the Out-Of-Memory killer.

Here's a post with more detail, from a former co-worker of mine:

But if they're offering Xen now, things may be better.  For me, the 
problem was obvious, so if you're happy with the Xen instance, they're 
probably OK.

I seem to recall that Steve was hosting some Xen instances for people; 
if you're looking for something a little more robust than the 
bargain-basement mass-market hosting, that might be an interesting route 
to take.  OTOH, I may be mis-remembering, or something may have changed.

I ended up on RimuHosting, which is working out for me.
