Can anyone recommend a site uptime monitoring service

Lots out there but has anyone gone through the process and found one that they rate.



Thanks.

I can highly recommend Siteconfidence for an external provider offering site uptime / payment processes etc etc.



I currently employ them to work on all the sites owned by Norwich Union and they can work on a fixed monthly cost or cost per transaction for cart testing.



Not cheap, but should give you a benchmark for external companies.



Hope this helps
