How to get SMS notifications when your server is down (in Europe)
With that in place, go create an account at Clickatell or a similar SMS gateway. Folks in the US needn’t do this, because SMSes are paid for by the recipient, not the sender, but here, you have to use a gateway so you have someone to pay.
Now, finally, go to uptime and use the email
firstname.lastname@example.org. Once created, go edit the parameters. Choose Periodic, and enter the following body for the email, using your own values for the different fields:
api_id:XXX user:yourusername password:yourpassword to:yourcellnumber text:Yoursite.net is down
That’s it, you can now look forward to getting SMS messages in the middle of the night. Enjoy! (Thanks to Claus Rasmussen for pointing me to clickatell.)
