OS NGD planned maintenance - Update

Planned maintenance: Sunday 13 July 2025 to Friday 18 July 2025

Impacted data

For the duration of the planned maintenance period, the following OS NGD collections will not have surveyed change updated daily:

  • Building Features

  • Land Features

  • Land Use Features

  • Structure Features

  • Transport Features

  • Water Features

All feature types in the aforementioned OS NGD collections will be affected by the planned maintenance period.

Duration

We have a period of planned maintenance for the OS NGD scheduled to take place from Sunday 13 July through to Friday 18 July 2025, at the latest.

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.
