Countdown data jumping around

Open Data
1

Since TfL brought back the data feeds after the cyber incident, we periodically get reports from users that the live data keeps jumping around and doesn’t match. By period i mean it only happens on some days (no trend has emerged).
For example, we got such reports on

  • Fri 25 Oct
  • Tue 29 Oct
    and several occurrences in November.

Do you know more about this?

Thank you!

Hi Nick,

Do you have any examples?

I know that sometimes near the beginning of a route, you get some issues if the driver is delayed starting the route.

Many thanks,
James
