Today in love jujube newspaper saw, very easy to use: http://www.siteuptime.com/
After the website goes down, you will be prompted to receive emails.
Available Monitoring Options
* HTTP: Web Server
* POP3: Email Server
* SMTP: Outgoing Email Server
* FTP: File Transfer Protocol
* SSL: Secure Socket Layer
* DNS: Domain Name Server
* Custom TCP Ports
* Ping
* Web Page Content
* HTTP Password Protection
In the past, I also prepared to do something in this area by myself. It would be better if I could add text message reminders and other functions.
(In this case, can I bind a robot to remind me ?)
Free Service each account can provide one monitoring. The $5 billing method has three monitoring items per month, and more functions (too expensive ...)
However, you can register multiple accounts and send a prompt email to the same email address (this seems a bit embarrassing :)
