This thread is for updates on the ADS-B Statistics which are viewable at flightaware.com/adsb/stats or on your own “My ADS-B” page.
Statistics are calculated and updated on the web site on an hourly basis. During busy times statistics may get more than 1 hour “behind” real-time. Over time we address this with the addition of more hardware and further performance optimizations of the software.
3-Apr-2017 - Additional hardware deployed to support the continued rapid growth of the ADS-B network. We are adding over 100 new sites per week.
4-Apr-2017 - An issue has been identified where some sites’ statistics are not updating properly after the maintenance performed yesterday.
6-Apr-2017 - All known issues with statistics calculation are resolved as of around 16:00Z. Statistics should start generating in the next hour for sites that were experiencing missing stats. We are looking into filling-in missing daily stats for sites that experienced issues this week.
10-Apr-2017 - Stats for the April 3 and 4 were restored over the weekend. Stats for April 5 and 6 are incomplete and not yet recalculated.
12-Apr-2017 - Stats for April 5 and 6 are being regenerated.
13-Apr-2017 - Stats for April 5 are restored.
18-Apr-2017 - Stats for April 6 are pending while we make some further optimizations and perform testing.
2-May-2017 - Some users are reporting isolated issues with hourly or daily stats not appearing on their My ADS-B page. We are investigating this issue.
11-May-2017 - The issue with isolated stats missing in one-off intervals has been identified and a solution is under development.
16-May-2017 - Isolated missing stats issue has been resolved on a go-forward basis. Please report any further issues on this thread.
20-Jun-2017 - There are two known issues being investigated by FlightAware: low hourly counts in apparently random hours of the day (sporadic) and stats generation running more than an hour behind real-time during peak hours of the day for some sites. We are aware of the issues and working to address them with long term fixes.
7-Aug-2017 - All known issues with stats calculation have been resolved and scalability for future growth has been significantly improved.
Even though the stats may not be updating for your site, your data is still being received and captured by FlightAware for flight tracking (barring any other unrelated issue that your site may have at the time).
