Contractors on behalf of ITaP Networking will be upgrading
network infrastructure in HAAS on the evening of April 1 from
11PM until April 2 6AM. There will be general network
disruption.
After the update it will be necessary to make manual adjustments to network switches in a couple of the rooms -- HAAS G049 and HAAS 145. ITaP Networking will be over first thing tomorrow morning to make the adjustments. Until they do, the machines connected to the in-room network switch will be off the network. This includes laptops using the wired connections.
Update@7:30AM: work is taking longer than expected. Estimated time of completion is 9AM

Update@12:30PM: The backend devices and server in HAAS 257 (XINU lab) back on-line.
