tl;dr: Starting on Wednesday, the Horizon UI is going to look a bit
different.
--
On Wednesday next week I'm going to switch Horizon and Toolsadmin
traffic away from their current physical host and over to new hardware.
The change to Toolsadmin will be largely invisible, but the Horizon
switch will include a two-version upgrade from (alphabetized) version
'Mitaka' to version 'Ocata.'
If you'd like to try out either of the new services, they have their own
temporary public urls:
https://newhorizon.wikimedia.org/
https://newtoolsadmin.wikimedia.org/
I welcome your comments, either positive or negative. A few of
Horizon's workflows have moved to client-side javascript, so bits and
pieces may be a bit more responsive but in general it will still provide
the slow load times that we've all learned to tolerate.
In addition to UI changes, behind the scenes these new sites are quite a
bit different:
- Both services are running Debian Stretch (the old services were on
Ubuntu Trusty).
- The services are running on a pair of new servers running behind a
load balancer, which should reduce downtime during future maintenance.
- The new Horizon deploy is deployed using Scap3, directly from the
upstream source. That will make applying future WMCS-specific fixes and
improvements much simpler.
