I signed up with a test address and it seems to be working as advertised. However, they require an email address and I have no idea if the whole thing is really a front for spammers (I signed up using a special address so I'll let you know).
Does anyone have any more information on this company or other free cron services that we can recommend?
I use Directupdate (http://www.directupdate.net/) It is a program for updating dynamic dns-servers, but it has a function to trigger a webpage and it has a timer, so that's al you need. It runs as an NT-service.
Only available for win32-machines.
Shareware, fully working without restrictions or timelimit, 15$ registrationfee
Here are some more german services for free cronjobs.
I've looked for more informations about cron24.de. I found no negative informations. But I found also no informations about spam
if your looking for an english cron solution use http://www.webbasedcron.com
it's $8.95/USD for the year and you can set cron jobs by the minute, hour, etc.
Your email is only used if you want to be notified when your cron job is run.
Good luck with all your projects,
How did you get on with cron24.de?
I could use a service like this for one of the projects I'm working on.
