Response

1. What exactly was/is this anomaly?

2. What is the scope of this problem and where exactly has been impacted?

We can confirm that we do hold the information. Under Section 21 of the Act, we are not required to provide information, which is already reasonably accessible to you. The information you requested is available via https://www.gov.uk/guidance/nationalhighways-variable-speed-camera-anomaly, https://www.gov.uk/government/speeches/speed-enforcement-on-the-strategic-roadnetwork and https://nationalhighways.disclosurelog.co.uk/disclosures/771656a94695-4f53-836f-ae70c012105e?preserveHistory.

3. What is the timeframe for this issue i.e. when did it start and is it resolved now, or still ongoing?

As above, the timeframe is already reasonably accessible to you under Section 21 of the Act. The information you requested is available via https://www.gov.uk/guidance/national-highways-variable-speed-camera-anomaly and https://www.gov.uk/government/speeches/speed-enforcement-on-the-strategic-roadnetwork.

We can confirm that there are no longer any activations leading to the erroneous enforcement of variable speed limits.
