To suggest a service that I have no relation to (other than being a happy
customer), have you looked at Pingdom [http://www.pingdom.com/] ? I'm not
using the DNS check type, but I have a dozen or so HTTP checks there.
Their system is super simple, no frills, and is priced like it :) It
looks like you can list a domain to test, a server to check and what
result you expect. They run checks from a bunch of different places (40
servers, seemingly half in the US, right now). Pricing at the low scale
is $6/check/year, which is pretty compelling even against running some
VPSes if you aren't checking too many sites.
