On Monday June 1st, 2015 ITS will be updating the Sites at Penn State WordPress core. Alongside this update a lot of themes as well as plugins will be updated. As part of this update there is a database update that will be taking place across two nights (June 1st and June 2nd) during off peak hours starting each night at 12:00am and ending at 7:00am each morning. Users should experience little impact as the more database intensive part of the operation will be taking place during off peak hours.
