I’ve heard a lot about it but never tried it yet. gonna try it soon. Thanks for reminding me.
Cool…. i have already set up pingdome for my site and it surely helps me to see whats going on in my server!
Nice info. There are several such tools and I think currently Pingdome is the best. Thanks for sharing.
your most welcome
Absolutely. It takes few moments to set everything up in Pingdom but once done it is a great tool to monitor your blog/site!
yes it really works out well
I moved from Pingdom to Dotcom-Monitor last year and I am sure the latter service is much more suitable for mid & large organizations.
