Evergreen database maintence is planned for Monday, February 20th (President’s Day).  Evergreen will be down while we upgrade Postgres and the operating system on the database servers.  This process will start early in the morning and we expect to be back online by mid-afternoon.  All Evergreen services will unavailable while we upgrade the database.  This includes the client, OPAC (our on-line card catalog), and authentication via SIP (OverDrive, Commonwealth Catalog, etc.)  During this time, we will be unable to place holds, renew items, or download e-Books/e-Audios.
