Resolved (May 27, 8:30 p.m.): Mailman services have been restored. Users who tried to send an email message using Mailman lists on Monday, May 27 between 8:00 a.m. and 8:30 p.m. will have to re-send the message.
Update (May 27, 1:38 p.m.): the Mailman system maintenance is expected to take approximately 6 hours. Mailman is still unavailable.
What is happening? An issue is preventing users from accessing their Mailman accounts. Maintenance is currently being performed to fix the issue. In flight email destined to a list will be stored at the
sender and will resume normal operation when the system is restored.
What is the impact? Users are not able to send or receive emails from Mailman lists.
What is it? Single sign-on (SSO) provides a secure method of accessing multiple web-based systems and applications without being required to log into each one. Enter your credentials once and move seamlessly between supported applications.
Benefits of single sign-on: With single sign-on, users will authenticate once, saving time as they move more securely and efficiently between applications.
