We are now offering a download of pre rendered tiles up to zoom level 17 on https://tile.osm.ch/tiles.html. The tiles are split up into the cantons as the whole of Switzerland is quite a large amount of Data.
You can download them to either host them yourself, or use them in an offline application.
The default style on osm.ch now includes contour lines and is updated to the latest version of the openstreetmap-carto style sheet.

The 2018 AGM will take place in Solothurn on April the 7th, 11:00. The venue is at the
Amt für Geoinformation
Rötistrasse 4
4501 Solothurn
Many thanks to SOGIS for supporting us
The event will follow our proven formula with a roughly one hour formal part starting at 11:00, with lunch following and a fairly unstructured mapping party as the activity in the afternoon from 13:30 onwards.
Guests, including such that simply want to learn something about OpenStreetMap, are welcome to both parts. Could however both members and guests indicate to info@sosm.ch if they plan to attend, particularly for lunch, so that we can inform the restaurant how many guests they can expect.

There are two planned power outages:
Due to construction work in the building where the SOSM servers are located. All SOSM services are unavailable during that time:
On Friday October 20th, a delegation of three members of the Swiss OpenStreetMap Association had the pleasure to receive the DINAcon Open Source Hero Award for OpenStreetMap long term contributors.
DINAcon 2017 Open Source Hero Award for OpenStreetMap Longterm Contributors.

In its laudation, the jury acknowledged that the work on OSM is a continuous process and a lot of manual work, and that a lot of persistence was needed to get the project to the state it is today. This award was accepted in the name of the whole Swiss OSM community and the OSM community world wide.
overpass-turbo is an easy to use data mining tool for OpenStreetMap. To reflect the continued improvement of the tool, we have updated this software on the SOSM servers to the latest version. Thanks to Martin Raifer who is the developer of this tool.
routing.osm.ch also got an improvement: Now the link to the debug map works correctly and shows the routing speeds and turn weights used by the currently selected profile.

We had a server outage from Saturday evening June 24th until Monday afternoon June 26th. The main reason was that three disks had failed in the production server and had to be replaced. Fortunately, we had enough spare disks. Sorry for any inconveniences this outage has caused. Everything should be back to normal now.
Some of the SAS (this is a fast computer interface similar to SATA) disks we received together with the servers that we run osm.ch and related services on, have failed due to old age, and while we originally had an ample supply of spares now we’ve now run out.
Unfortunately, these disks are rather expensive to purchase new, if not to say uneconomic. Luckily Metanet has now helped us out by donating eight 2nd hand disks from their stock. This will allow us to defer a complete replacement for at least 1 to 2 years and make an unhurried decision on what to buy.
A big thank you to Metanet for supporting the Swiss OpenStreetMap Association.
Update: the old interface is turned off. The new one is available at routing.osm.ch
There is a new routing user interface for osrm which I am testing at routingnew.osm.ch. I would welcome feedback here as a comment or on the Swiss mailing list.
There was no easy way forward. A little background: Last year, we bough some shiny new SSDs to speed up our servers.
I decided to install the new Ubuntu 16.04 onto the new disks, the new long term support version. In the mean time, most services are moved to the server with the new Ubuntu and the SSDs, except routing. I couldn’t get our old version of OSRM to run on Ubuntu 16.04, so I was forced to upgrade to the newest version. But a lot was changed in OSRM in the mean time: the API for routing requests as well as the syntax for the routing profiles. That is the main reason why we still run such an old version. The old user interface we used is no longer maintained, therefore incompatible with the current API. But there is a brand new one, which does not support multiple routing profiles. So starting at the hack weekend in Karlsruhe, I hacked the profile selector into the new interface.
The plan is now to switch to the new OSRM and user interface on Sunday, March 19th.
