The Colorado Alliance of Research Libraries is making changes to the underlying architecture of their website. The Alliance hosts Prospector (the Colorado unified library catalog) and Gold Rush (our journal/article finding service).
Here is the information from the Alliance:
On Monday, December 17, 2007, the Prospector system will not be operational since a network upgrade is planned. Prospector is hosted by the Colorado Alliance of Research Libraries and on that day the consortium will be installing a newer higher capacity Internet connection through a new Internet Service Provider (ISP). The outage will start around 8am in the morning and Prospector, along with other services hosted by the consortium, will be out most of the day.
