We are starting upgrade maintenance on our Shared MS SQL servers tonight (07 Nov 2016) at 23:00.
The first server being upgraded is mssql43.cp.blacknight.com (a.k.a. mssql43int.cp.blacknight.com). The MS SQL service will be unavailable on this server for 1-2 hours.
Over the coming days we will be upgrading more Shared MS SQL servers. So please keep an eye on our status posts if this maintenance will affect any of your databases.
