We have been informed by our supplier that they intend to carry out maintenance within their network. The purpose of this work is to carry out network development.  During the maintenance window you may experience one period of outage to the maximum specified below.

Detailed Description of Request:

Openreach would like to remind Customers of the benefits of planning their release schedules carefully during this period; and to monitor Openreach outage and service communications accordingly.
