If you're running CentOS 5/6 or RHEL 5/6 and have need for a recent Tomcat version, you're most likely familiar with the jPackage repositories. In fact, just about any guide you may find in the interwebs will point you to that repository for up-to-date packages.
It's not that convenient that the repository is offline then, is it? With no sign yet on when it's coming back, we dedicated to announce our own jPackage mirror for the time being, until the official ones come back. It won't be updated (since the upstream appears to be dead), but for new installs it may still be usefull.
You can find the mirror at http://mirror.nucleus.be/jpackage/, with an example Yum Repository file included.
Hope it helps!
