Whidbey certificate expired but purposely not renewed

Posted on by

I have the valid certificate ready but not installed for the following reasons.

  1. There should be no known application using the Certificate.
  2. In the past, the Certificate has been renewed, not knowing it’s used or not, just for the precaution.
  3. Before not renewing anymore, I need to make sure the Certificate is not really used by any of the applications.

[Completed] ResNet Bandwidth Upgrade 3/24/09

Posted on by

[Update 3/24/09 6:00 AM] The bandwidth upgrade on the ResNet Internet connection is complete. ResNet now has a 100 Mbps connection to the Internet. Enjoy!

On Tuesday morning, 3/24/09, from 5:30 AM to 6:00 AM the Internet connection for the college’s residential network will be upgraded from 45 Mbps to 100 Mbps (a two-fold increase). The Resnet Internet connection will be unavailable during this time.

The upgraded connection will feature not only a 100 Mbps bandwidth, but also a new traffic shaping model, based on bandwidth, rather than type of traffic. This should reduce many of the application problems we have seen over the past few years.
