OS NGD planned maintenance

Upcoming planned maintenance: Sunday 9 November - Tuesday 11 November 2025

We have planned maintenance scheduled from Sunday 9th of November through to Tuesday 11th of November 2025, at the latest, for the OS National Geographic Database (OS NGD).

For the duration of the planned maintenance period, the following OS NGD Collections will not have surveyed change updated daily. All feature types in the following OS NGD collections will be affected by the planned maintenance period:

• Building Features

• Land Features

• Land Use Features

• Structure Features

• Transport Features

• Water Features

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 OS NGD APIs, will remain uninterrupted, but data for the affected collections will not reflect daily surveyed changes.
