website downtime monitor with sms/email notifications?
 

Don't you just love NOT knowing that your website is down?

Is there like a service (free one) that monitors your websites and if they're down sends you notifications?

Email is fine, I can forward it to sms.

Been using them for a while, they have free and premium plans

Alertra is very good, notifies you via email, SMS, phone call, or instant message, however you want.

Not sure if this one is still supported but there's always Choker's Better Be Up.
