This just in from CSA:
On Saturday and Sunday, May 10th and 11th, 2008 some CSA Illumina
services may be affected by maintenance procedures. During this time,
you may experience intermittent slow service while using the CSA
Illumina platform or your federated search client (Z39.50). My Research
and the Administrative Tools will be unavailable for part of this
maintenance window but we will do our best to minimize the impact to CSA
Illumina services.

Please share this information with your colleagues.
