Pingdom Pro Accounts – Giveaway
I have been using the free version of Pingdom for more than a year now, along with a couple of other website monitoring tools, and it has almost always been first in reporting the downtime (as well as uptime) of my site.
The basic version is free but if you would like to track more than one website with Pingdom, you'll to upgrade to a Pro account and that costs around $10 per month.
We have some 20 discount codes that will get you one-year of Pingdom Pro at 100% discount. In case you would like to have one, fill this Google form and if you are lucky, you'll get the code via email.
