If all goes well with the Sierra 2.1 upgrade tomorrow, we hope to follow that with an Encore upgrade on Monday, February 8th. The upgrade will take place at 7:30 am and should take less than 30 minutes to complete. If all goes well, the Encore server should only be down for a short time and be back up by 8:00 am. The Encore update will will not affect the Sierra server, so all Sierra activity can take place as normal.
The Encore upgrade will provide a better patron account view in Encore mobile, will add a genre facet to the Refine by section, and, so I have been told, fix the issue that has kept us from being able to link to the Digital Public Library of America in the Articles search.
