Over the last few years, Pingdom has established itself as a well-regarded uptime monitoring service, but until now, its services were only available to paying customers. Today, however, Pingdom launched a free version of its service. The free service offers all the features of Pingdom's paid accounts, though users are limited to monitoring just one website or server. This free account also comes with up to 20 SMS alerts per months, which is a nice perk, given that you probably want to know that your site or server is down as soon as possible.]]>
Pingdom gives users a large number of options. You can, for example, choose to have it ping your server anywhere between once per minute or once per hour. Pingdom is also flexible enough to be able to ping specific ports on your server and also check the state of your SMPT, POP3, or IMAP email server - though with the free account, you can obviously only choose one of these.
In addition to its free service, Pingdom also offers a basic account for $9.95 per month, which allows users to monitor up to 5 sites. The company also offers a business account for $39.95 per month, which can check up to 30 sites. The basic account also comes with 20 free SMS alerts, while business account users can receive up to 200 alerts by text message.
