What maintenance is taking place?
During the maintenance period, OS will be delivering data improvements to the OS NGD. More information on these improvements can be found on the OS NGD Improvements page.
Impacts to customers
All daily Change-Only Update (COU) orders will continue to be delivered and processed as usual. Files for the affected collections may be smaller or empty for the duration of the maintenance period. If your order includes both affected and unaffected collections, the unaffected collections will continue to receive daily updates.
Access to OS NGD services, including OS Select+Build and the OS NGD APIs, will remain uninterrupted, but data for the affected collections will not reflect daily surveyed changes. When the maintenance period ends, you may notice a larger COU file for the affected OS NGD collections as the surveyed change during the maintenance period is made available.
