Communications to Users

See this article in context within the following user guides: Eos | Titan

The OLCF provides users with several ways of staying informed.

OLCF Announcements Mailing Lists

These mailing lists provides users with email messages of general interest (system upgrades, long-term outages, etc.) Since the mailing frequency is low and the information sent is important to all users, users are automatically subscribed to these lists as applicable when an account is set up.

OLCF “Notice” Mailing Lists

The OLCF also utilizes high volume mail lists to automatically announce system state changes as well as other notable system events. Users who are actively using a system are automatically added to a system’s mail list.

When a system changes state (up to down or down to up), an automated email is sent to members of the system’s notice list. We also send additional notable issues and time sensitive events to the list.

Available Lists

Users can request to be permanently added or removed from a list by contacting the OLCF User Assistance Center.

Weekly Update

Each week, typically on Friday afternoon, an email announcing the next week’s scheduled outages is sent to all users. This message also includes meeting announcements and other items of interest to all OLCF users. If you are an OLCF user but are not receiving this weekly message, please contact the OLCF User Assistance Center.

System Status Pages

The OLCF Main Support page shows the current up/down status of selected OLCF systems at the top.


The OLCF posts messages of interest on the OLCF Twitter Feed. We also post tweets specific to system outages on the OLCF Status Twitter Feed.

Message of the Day

In addition to other methods of notification, the system “Message of the Day” (MOTD) that is echoed upon login shows recent system outages. Important announcements are also posted to the MOTD. Users are encouraged to take a look at the MOTD upon login to see if there are any important notices.
