The old groovyblog's hosting provider stopped their sponsorship on Sept. 1st. Since then we have been working hard on getting it back online.
We are reusing the code that Glen Smith wrote (running on Grails 1.2) and are revamping it to run on the latest Grails. This takes a little time, so please bear with us.
The good part is, that the feeds are running again and that you can read the RSS feeds again.
