Planned maintenance to some of UCAR's computer room infrastructure will require Unidata's web site, FTP server, email, and mailing lists to go off-line temporarily on Saturday, April 28th 2012. Maintenance will occur between 6:00am and 3:00pm Mountain Daylight Time. Network downtime for the affected systems is anticipated to be approximately two hours starting at 6:00 am, but since the computer room's uninterruptible power supplies will also be serviced, a power outage any time during the maintenance period could cause additional downtime.
Unidata Program Center staff are working to ensure that other Unidata services provided by hardware on the UCAR network remain on-line during the the outage. We expect that the UPC's Internet Data Distribution nodes, as well as the Motherlode server, will remain functional throughout the upgrade.
Thank you for your patience.
