Residential Internet Service Degradation 8/29/2014 [Resolved]

We will be doing some configuration changes to the residential internet this morning to solve some service degradation (slow internet speeds). This may cause some short drops in the residential internet during this time. This affects only the residence halls, houses, and Union Ave. fraternities and sororities; academic and administrative internet connectivity will not be affected.

[Updated 2:00 p.m.] Configurations were completed around noon, and the residential internet is returned to full service. Thank you for your patience.

Scheduled Maintenance on Core Router

I will be upgrading the IOS on our Core Router (Cisco 6905) at 5:00am tomorrow morning (Tuesday Feb 8th).

The upgrade is to enable a new 10GB interface slot card.

All preparations are already in place, so I expect the downtimes to be short (5-10min each) and intermittent between 5:00-6:00am.

During the downtimes, all inter network-connectivity will be disabled.  There will be no access to any services or resources during this time.

This will include but not limited to: email, internet, databases, VPN, etc.

[Completed] ResNet Bandwidth Upgrade 3/24/09

[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.

Aruba Wireless

Some users were not getting IP addresses when connecting to Aruba Wireless.  This was do to a shortage of IP addresses in DHCP.  I expanded the scope on Saturday to make more IP addresses available.  This problem should not reoccurr.

Resnet DHCP Server Problem Resolved

A number of people in Resnet, mostly centered in the Langlow subnet, but not restricted to that area, had been reporting receiving invalid IP addresses, even though they had successfully registered their machines. The dhcpd.conf file had valid bootp entries for these machines as well. An astute student gave us a crucial piece of information – students that had registered after a certain time (unclear, but probably last week) were having the problem, while students resgistered before that time were working properly. This led me to believe that the dhcpd daemon was not running with the current version of its .conf file, and that a restart of the daemon would resolve the problem. When we attempted to restart the dhcpd process, it was found that the restart_dhcpd perl script was not running, whihc would explain the problem. Upon restarting the dhcpd, the problem was resolved.
