Software to check status website

I'm owning about 150 websites and tired to check if they are still online. Is there any software available that can connect to those websites to check if they are still online. (Need some windows based software)

Thanks,
Wiper

 

I assume nobody knows how to perform this task.

 

Put an automatic payment for your hosting, and when the period that you have paid for expired, the web hosting company will automatically charge your card for the next period.

 

There are some free and paid services online that monitor if your site is online by visiting it periodically ( every 15 minutes, harlf an hour etc..) and they will inform you whenever your sites go offline.
example: siteuptime.com, freewebmonitoring.com, host tracker, etc...

 

Try basicstate, but it sometimes gives false alarms

 

Thanks for the reply. I will try one of them.
