Web-CAT is still active. All of the static resources on this site, including software updates, our Eclipse update site, our workshop materials, and other resources continue to remain available.

Only the dynamically generated community portal providing our discussion forums and wiki pages is down for maintenance.

Our community portal will be back online soon. Thank you for your patience as we migrate to a newer version of our website tools.
