This week I got an email from the Pingdom CEO mentioning that they are now offering free accounts. That is good news for all small bloggers out there.
Pingdom is basically an uptime monitoring company. In other words, after you create an account with them, they will monitor your website. Should it go down, they will immediately notify you about it, either by email or by SMS (or both). The service can check if your website is up every minute if so you specify, and they make tests from several locations around the world to make sure it is really down.
Until last week you would need to pay $9.95 monthly for a Basic account, which can monitor up to five websites. Now they introduced a Free account (which is not a free trial, but a standard account). The only limitation is that it can monitor only one website. Other than that, you have access to all the features.
I just signed up and added Daily Blog Tips to my account.
