Exchange front-end server OWA disk failure

by

We are rebuilding OWA after a disk failure. Exchange service through OWA (e.g. web access, or mobile client access) will be unavailable in the meantime.

Access via Outlook directly to FONTUS from machines on the EECS network may remain available, unless configured to access OWA using RPC-over-HTTP.

Third Unplanned Power Outage to 165 Cory

by

Report from Scott McNally:

“Power was just lost again at 3:40pm Wednesday, 4/10/13. We will have to triage the number of machines we allow on in this room once we restore power. Then we still have a power shutdown on Friday to replace the faulty breaker.”

Mailed earlier today to the Cory Sysadmins maillist:

“Campus is planning a shutdown of Electrical Services to Computer Machine Room 165 and the East Side 1st floor of Cory Hall on Friday, 4/12/2013, between the hours of 9am-Noon to replace the faulty breaker. We are currently operating critical equipment only in room 165. In fact we insist no additional equipment be turned back on at this time until after the repairs on Friday can be made. If you are able to shut down equipment that may not be needed between now and Friday, we ask that you do so.”

Partial Power Failure in 165 Cory Machine Room

by

Due to a Power Distribution Unit or the UPS failure in 165 Cory Machine Room, there is limited to some servers located on the east side of that room.

The Building Manager has a call in to campus to fix the PDU and we’re in a holding pattern until then. Building and technical staff are working to restore everything as soon as possible.

When there is a update, it will be posted here on IRIS NEWS.

Mail delivery to Exchange accounts stuck

by

The BWRC Ironport anti-spam appliance, which processes email for EECS Exchange server FONTUS as well as the BWRC Exchange server, started deferring new mail delivery sometime Saturday evening.

Exchange users would notice no new email in their accounts, and senders would receive a notice that their message was temporarily deferred. Mail delivery is only deferred; it should be correctly delivered once the issue is resolved.

Exchange email delivery issue

by

As announced previously to EECS/BWRC Exchange users, the BWRC IronPort anti-spam appliance was scheduled to be moved to the campus datacenter this morning, with downtime expected between 6 am and 7 am.

Kevin Zimmerman has run into some problems getting the IronPort properly installed in the new location, and is working with the vendor to seek immediate resolution. Failing a quick fix, the IronPort appliance will be returned to its previous location, to restore Exchange email delivery service.

The BWRC IronPort generally handles all incoming EECS Exchange email, filtering out lots of spam. For the interim, I have updated forwarding for FONTUS Exchange users, so that new email as of 8:16 should go directly to FONTUS. This will allow normal mail delivery for FONTUS users, but will likely result in a temporary increase in received spam.

No mail will be lost. Email sent during the downtime will be delayed. BWRC Exchange users will continue to have mail delayed until the IronPort is back in service.

Thank you for your patience.
