I can second the Linode suggestion. I have multiple Linode VPS running, and have been a happy customer since 2005.
If you have multiple servers, they pool the bandwidth allotments together into one and let each share them.
This is very handy as one machine of mine regularly exceeds its individual allotment, but the other 4 are always around 10-20% each month. The "unused" bandwidth on those other machines goes towards the one heavy web frontend and I never exceed my total monthly (Which I believe is at 800 gb/month at this point)
They also regularly "gift" extra ram and storage to you after your first year of service. Typically at christmas I get another 10% storage for free, and in June I get another 10-15% ram for free. The ram kicks in automatically at next reboot, but the storage you need to expand yourself.
They also ksplice in kernel updates, meaning you do not need to reboot to have your kernel patched with the latest security updates.
If you use a debian/apt based linux distro, you can keep userland updated without reboots as well, and gain some amazing uptimes while still being fully patched.
My highest uptime right now is 837 days. My record uptime with them is over 1600 days.
In addition, they allow you to use an additional "private" ethernet network to link your linodes together using 192.168.xx IP space (IE for MySQL to Apache links) and do not meter bandwidth over these interfaces. Even if the machines are in different datacenters.
For redundancy purposes I have servers in Freemont CA, Dallas TX, Atlanta GA, Tokyo JP, London UK, and Newark NJ.
I believe they have an Amsterdam datacenter as well (But I don't have a VPS there)
You can script the boot order of your machines, to assure your database backends are up before your webservers boot.
They can send alerts when your bandwidth or IO usage hits a certain mark, so you can look into whats going on, or set higher to know before you hit any limits that would cost you extra money.
There is also a web API to script control of the machines, if you're into that kind of thing.
They can do DNS for your domain(s) for free, and have an optional backup service (that isn't free) - Personally I run a
BackupPC server in my basement that runs backups once every three days or so. Just depends what effort you want to put in yourself, or how much you want to spend to save that time.
Unfortunately they recently changed their referral system. It used to be if you referred someone and they stayed for 90 days, both of us would get a $20 credit. Now it looks like only the referring customer gets the credit, and not the one referred :{
So in the sake of fairness I'll leave that one out.
None the less, I couldn't recommend them enough.
If you have any other more specific questions, just let me know and I'll try to answer as best as I can.
