In order to get the service more error prone, I added some logic to disable erroneous websites. Websites are disabled when the two last checks failed and in total 75% of all checks failed.

Users are able to re-enable the site by just editing the entry in their list. At that time the website is verified, and when successful it is enabled again.
This update will also be applied on the cron module.

After the update of drupalcron to support the cron_key for drupal 7 it is time to apply those changes to the cron module.
Also the added curl options at drupalcron are added to the cron module.

Today I had some time to update drupalcron.

Bugfixes:
Change of curl options to solve problems with unreachable sites

New features:
Support for drupal 7 cron. You're now able to add the in drupal 7 added cron_key.

Today I noticed that the 100th site was subscribed to Drupalcron.org.

Hopefully this is only the first milestone we could reach with this service.

One thing is sure, the idea is a success. Not only is there the admintools module that enables you to do the same as Drupalcron.org for your own, Acquia made this also a feature of their 'Acquia drupal'

At request I've added the cron module to drupal.org. It's named admintools, cause I plan to make more tools for the admin of several drupal installs. So more news will follow soon on that.

A drupal 5 version of the cron module will follow shortly.

You can find the module at: http://drupal.org/project/admintools.

After speeding up some things, it's time to attract a bigger audience. Drupalcron.org will provide the drupal admin with a cron visit every hour. No more cron configuration. Just create an account on Drupalcron.org and you can add 5 drupal sites to your user account.

If you administer more then 5 drupal sites, and yet you want central administration and still no cron configuration you can download and install the cron module. This allow you to add countless sites, to be visited when the cron of the on which the module is installed is executed. If you add that site to Drupalcron.org, all your sites crons will be executed every hour, without any configuration of cron.
