What SetCronJob promised

SetCronJob promised:

- 99.9% uptime
One month has 30*24*60*60 = 2592000 seconds, and 0.1% of this is 2592 seconds, or ~ 43 minutes downtime in one month. This is to maintain scripts, httpd, server, etc.

- 99.0% your script will be executed within 60 seconds from set time.
E.g your script should be executed at 1:15 AM. So, it may be executed at time between 1:15:00 and 1:15:59 AM

- 99.5% script will be executed
Your script will be executed whenever your web server is up, allows SetCronJob to call script, and your script returns status HTTP/1.1 200 OK. The connection time out is 2 seconds.

- 99.0% number of times your script will be executed.
One days, my cron daemon will be launched (60/5)*24 = 288 times. SetCronJob promised 286 times a day (down 2*30=60 times a month).

This is promise for both free and paid service. Above numbers are what I did promise. The real values may be higher.

How to disable a cron job?

Simply click on Disable icon. Your cron job will be disabled, and no longer be executed.

For Unix/Linux users, you can simply edit your crontab file (using crontab -e), and add # at beginning of cron job line you wanna disable.

For example, you have this cron job:
*/5 * * * * lynx http://example.com/backup.php
And you wanna disable it. Change it into:
#*/5 * * * * lynx http://example.com/backup.php
