Due to a failure of our LDAP servers, the work announced below has been postponed to Tuesday, December 10, 2013, from 7:30am-8:00am (10 Gb/sec link) and Thursday, December 19, 2013, from 6:30am-8:30am (switch updates).
Who is affected:
All users of CS Department wired networks, including network users in the CS Building, 221 Nassau St, Sherrerd Hall, Friend Center, and 151 Forrestal Road (the HPCRC).
This outage will also affect the OIT wireless network ONLY in the CS Building.
What is happening:
During this time, the Department\’s network uplink (to the main campus, and onward to the greater internet) will be upgraded from its current 1Gbps link to a 10Gbps link.
Also during this downtime, several network switches will be updated to newer versions of their operating systems.
Actual outages are expected to be much shorter than the full window, but outages local to any particular location will occur at various times throughout the window for 5 to 10 minutes at a time.
Why is it happening:
The campus uplink upgrade will enable greater opportunities for collaboration by increasing the rate at which data can be moved across the network. This will enable high-speed data transfer between CS Department systems and systems in other departments on campus and, in some circumstances, other remote locations.
The switch software updates will address a few minor bugs which have come up lately.
