Sympa mailing list service (Aug 19, 2014)

2014-08-20T13:22:44Z

Yingw:

'''As of 4:10am PDT, August 20th, the Sympa mailing list service is restored to working order.'''

The Sympa mailing list service for ECE and most of the Faculty of Applied Science went offline at 9:39pm PDT, August 19th.

This incident was caused by a misconfiguration of the ECE load balancers which resulted in the load balancer taking over the HSRP VIP on the subnet used by services that are load balanced. This change did not impact services that are load balanced such as the primary ECE website. Unfortunately the Sympa mailing service is one of the few services not load balanced on that subnet.

ECE E-mail Service - Message Delivery Delays (Apr 24th 2014)

2014-04-25T02:54:06Z

Yingw:

'''The ECE mail delivery queue has been reduced to serviceable levels as of 6pm, April 24th, 2014. Mail should be arriving to your ECE mail Inbox as expected.'''

This afternoon, ECE’s email service experienced a demand overload, with a peak of approximately 3,000 queued messages as of 4pm. Users of this email service may have experienced delays when sending and receiving e-mail.

The IT Team enacted changes to manage message volume, and the mail delivery queue was reduced to tolerable levels as of 6pm, April 24th. Mail will now arrive to your ECE mail inbox as expected, with some messages arriving several hours late.

Unfortunately, Google has 'rate-limited' emails originating from the ECE mail server. Due to rate-limiting, email destined to Gmail may experience delivery delays. This rate-limit will be reduced when Google determines the ECE mail server to be safe. The IT Team has no resolution timeline from Google, but this has occurred in the past and is normally resolved within 24-hours.

If you have any questions, please don’t hesitate to contact the IT Support Team in MacLeod 105. With the mail service functioning normally again, you may also send your query to help@ece.ubc.ca

Thank you for your attention,

IT Support Team at ECE
