Please excuse multiple postings.


On December 10th, the Colorado Alliance of Research Libraries will be
upgrading its networking bandwidth to a 10 megabit per second line.  This
will represent a threefold increase in capacity which will improve
performance of all Alliance services including the Alliance Digital
Repository (ADR), Prospector, Colorado School of Mines Voyager System, Gold
Rush and other services.  This will mean that all Alliance services will not
be available the day of December 10, 2007 as we make the necessary changes
to our network.  


The new Internet Service Provider (ISP) for the Alliance will be the UCAR
Point of Presence (UPOP) which is part of the larger Front Range GigaPop
(FRGP).  Many of the Alliance member institutions are part of this network
consortium so that there should be substantial improvements in performance
to Alliance services because of the increased bandwidth as well as us being
"closer" to our members in the Internet neighborhood.


To do the upgrade, the Alliance is required to change its IP addressing
scheme. The IP address change will require that member institutions update
firewall settings, access scripts, embedded IP addresses for Prospector, or
any other area where the numeric IP address is used.  Sites using domain
names (instead of the numeric IP addresses) will not need to make changes.
Be sure to check with your network administrator or IT department to
determine any changes to your network that need to be made.


We will attempt to minimize the amount of downtime on December 10th, but due
to unforeseen circumstances, there could be outages extending beyond the
initial period.  More information will be forthcoming including the new IP
addresses assignments for Alliance devices.  Be sure to contact Tim Donnelly
([log in to unmask]) with any questions.
