OpenStreetMap Service Availability (2023-11-20 - 2023-12-20)
Posted by NorthCrab on 27 December 2023 in English. Last updated on 27 January 2024.I have started an independent collection of OSM SLA statistics. Approximately once a month, I will publish my results with the aim of enhancing transparency regarding the reliability of OSM services. I use uptime-kuma to run monitoring. I also verify connectivity with non-OSM services (to prevent false positives). The current configuration includes checking the availability of openstreetmap-website and openstreetmap-cgimap (API). Tile layer availability is not currently included in the checks. The health-check resolution is set to 30 seconds, and the checks are executed from a single server in the Hetzner datacenter in Germany. For the endpoint to be marked unavailable, two consecutive checks must fail. This should be well-representative of an average user experience.
Summary
Total API downtime: 2 hours 34 minutes 13 seconds
API SLA: 99.643%
Total website downtime: 43 minutes 15 seconds
Website SLA: 99.900%
Note that some functionalities of the website require API to also be available.

@TrickyFoxy Thank You! I wasnβt aware of that. I quickly compared the downtime on 12-03 for βWebsite HTTPSβ, with the official number being approximately 3 minutes and 30 seconds of downtime. However, during my observation, I noted about 27 minutes of unavailability. Perhaps, the official uptime checks are hitting some form of cache, or the downtime was more concentrated in the European region. The next month I will do a more in-depth comparison :-)

Then check out https://prometheus.openstreetmap.org

Thatβs a good suggestion! However, I donβt think solving this mystery is my priority or of significant importance. I just personally found it interesting :-)

12-03 issue was handled in this operations ticket: https://github.com/openstreetmap/operations/issues/1008
IIRC a well known company did some fairly extensive web page and API scraping over the weekend and was blocked subsequently. (Mentioned in another operations issue)

@mmd Thatβs interesting! Thank you for sharing. :-)

I checked both
uptime.openstreetmap.organdprometheus.openstreetmap.orgaround that day. I think both of them is pretty much consistent. Two spikes of downtime. First, 13:50 - 15:00. Second, 15:00 - 15:30.
