UCSC Genome Browser: New Euro server (affects custom tracks)

So there’s some news from the UCSC Genome Browser team. It’s great news for a better user experience–sharing the load on different continents. But the first thing I wondered about when I heard that was: what about sessions and custom tracks?

We tell people in trainings that they can share their sessions with colleagues around the world by sending a link. But now that link behaves a bit differently depending on where you are–I’m told that if I got a custom track session link from a European server user, I’d get directed to that one. So keep that in mind, and note that you might have to tweak things just a bit.

Whole announcement email from the UCSC announcement list:

The UCSC Genome Browser is pleased to announce the introduction
of a new mirror site to serve our users in Europe.  Genome-euro is an
official European mirror site of the UCSC Genome Browser, at
http://genome-euro.ucsc.edu. The server is physically located at the
Universität Bielefeld Center for Biotechnology in Bielefeld, Germany,
and is administered by UCSC.   Genome-euro is meant to be an alternate,
faster access point for those Browser users who are geographically
closer to central Europe than to the western United States.

All functionality will be the same as on the US server, although Custom
Tracks will not be transferred. Saved Sessions containing Custom Tracks
will require some manual intervention

When European users navigate to the US server home page and click
the “Genomes” menu item, they will receive a notification that they have
been redirected to the more geographically-appropriate server. They will
have the option to remain on the US server, as  described in our

The backup mirror in Aarhus, Denmark will continue to serve as a
emergency site in the event of the official sites in California and Germany

Thanks to Steve Heitner, Brooke Rhead, Galt Barber, Hiram Clawsen,
Jorge Garcia and the rest of the Genome Browser staff for engineering
and testing.

We wish to express our special thanks to our colleagues at the
Universität Bielefeld Bioinformatics, especially Jens Stoye, for making
this possible.
