OSMF updates/2021-08/Operations Overview
Ensuring the operation and smooth running of the XML editing API and data distribution services.
Below are topics as mentioned in Operations reports at the time of their publication. Please note that depending on when the reports were released, the information might have changed. Some points might appear in two sections.
New data center in Dublin
The OWG has decided to move a site UCL/Bytemark in the UK to Dublin, Ireland. Equinix DB4 was selected as the new site location, Hurricane Electric as the ISP. Like the existing site, the new one will have the resources to host the website if the Amsterdam site is down. All required hardware has been ordered to meet this requirement.
COVID and global supply chain shortages have resulted in extended lead times for purchases, so some hardware has not yet arrived.
2021-09 update: After months of planning, we now have server infrastructure in Dublin Ireland.
All new supermicro servers in the 2021 budget have been ordered. Some were scheduled for 2021Q4 and 2022Q1 purchases but were ordered sooner because limited component supply means the lead time could be up to 12 weeks.
In addition to Dublin setup and planned replacements, there are new servers for expanding the capacity of Nominatim (Geocoding service) and the Standard Layer. The geocoding expansion will be in Dublin, and Standard Layer in Dublin and Umeå, Sweden.
New planet servers have been ordered. Using an object store was considered to reduce server requirements, but a large disk server was decided on as the object store route would take an unpredictable amount of time to develop.
Two old HP servers in the US have been donated to OSGeo instead of scrapping them.
Standard tile layer
The standard tile layer has switched to using Fastly as the content delivery network rather than a set of donated machines around the world. This drastically simplifies administration and improves service in areas of the world that were underserved before.
In order to reduce mass tile downloading in violation of the tile usage policy, automatic rate limiting by IP has been implemented. This should not impact users following the usage policy but will limit the load a single abusive user can put on the system.
Two new rendering servers have been ordered. One is being installed in Dublin, the other in Umeå, Sweden. Two new rendering servers are running on donated hardware from Appliwave and AARNet. The AARNet server was previously a CDN server.
The planet distribution service provides planet files, replication diffs, changeset dumps, and other data dumps.
There is now official documentation of the state.txt format.
TODO: Add Discourse
The OWG has been testing Prometheus for monitoring as a replacement for Munin. We are currently experimenting with long-term storage of metrics with TimescaleDB and Promscale.

CyclOSM added as a new featured layer on www.openstreetmap.org

|Featured tile layers refer to the set of different map styles featured on the OpenStreetMap web site. These can be accessed and selected by activating the "Layers" sidebar and then looking under the "Map Layers" section. There are currently six layers featured, and of these the "Standard" layer is the default.
Proposals for new tile layers to be included on the web site may be added to the table on the OpenStreetMap wiki. Any such proposals must follow the guidelines for new tile layers. Other servers, not appearing on the main page but available to public are listed at osm:Tiles#Servers.
