Comments:

We are migrating Open Ondemand on Lighthouse from version 1.4 to 1.6 to fix a security issue. Users will not be able to use the service during the upgrade process but running jobs should continue to run, based on our testing. If you need access during this period of time, we recommend ending your existing job and resubmitting when the service is restored.
