DXC would like to inform our customers that we need to perform important system maintenance on the IMR (Insurers' Market Repository) application.

This will also impact the functionality of the the following related applications: XAG (Xchanging Acord Gateway), DRI (Document Repository Interface), Writeback, CAS (Claim Agreement Screens), DFV (Document File Viewer) and DMS (Document Management Service) services.

Therefore the IMR system will be completely unavailable and the other related applications listed will have limited functionality between Saturday 23 May 01:00 - Sunday 24 May 23:00.
