The following was posted on Rootsweb, which is the hosting site for the Roblee mailing list:
We have been in the process of improving the site throughout 2017, and as a result of an issue we recently became aware of, we have taken the site offline while we work to resolve it. We take the security of our contributors and our viewers seriously. We apologize for any inconvenience this may cause, but protecting our users’ personal information is our top priority.
Update: January 25, 2018
We have taken the RootsWeb Mail system offline for the next few weeks so that we can upgrade the Mailman system. Mailman is the software which runs the mailing lists. While the system is down, you will not be able to send or receive email. We thank you for your patience.

Great news on the progress of getting RootsWeb back online. Today, we are bringing WorldConnect, one of our most valued features, back online. As we make WorldConnect available, it will initially be in a read only state. You can now search for people and view information as you did in the past; but for now, we cannot accept new uploads or modifications to existing GEDCOM files. We expect to add this additional functionality in the coming weeks.
