Continued investigation of a hardware/software issue in the WiFi and

This will be done today at ca. 17:15. Some impact on the services
(WiFi, eduroam and NOMAD, and NOMAD on Ethernet) is expected but
unless unexpected problems occur, it should be short and limited.

  Switchbyte Kemi forskarhus 1:
  Under arbetet med utbytet av gamla switchar blir det ett korta avbrott på datatrafiken
  för respektive datauttag. Förhoppningen är att Wifi skall funger under kontorstid.
  Vi startar på plan 9 och avrapporterar dagligen hur arbetet fortskrider


  Notera att problem har förekommit i samband med hastigheten i datanätet
  höjs från max 100Mbit till max 1Gbit. I första hand kan man prova
  med att byta gamla kablar mellan dator och vägguttaget.


Replacing switches Kemi forskarhus 1:
  Replacing old switches will generate one short interrupt for each outlet.
  Minor interrupt on Wifi during non office time is expected.
  Work begins at floor 9 and daily reports will be sent.

  NOTE:  Problems have been seen when moving max speed from 100Mbit to 1Gbit.
  Some old cables can't handle Gbit speed. First step is to replace old cables
  between computer and wall socket.

One of our core network switches experience a hardware/software problems,
and we must restart a component to (try to) solve it.

This will be done at Wednesday, January 17th, after 17:00.

The computer network services will be down for 5-15 minutes in parts of the
EDIT- and M-buildings, as well as the link to Onsala Space Observatory.

On Wednesday January 24th, one of the authentication backends for
WiFi (eduroam and NOMAD) and NOMAD on Ethernet will be upgraded.

We do not expect any service impact, but redundancy will be lost
during the maintenance.

We've for some time experience a hardware/software problem with some
components in our WiFi system (and NOMAD on Ethernet).

To solve this, hardware will be replaced. This will be done at Monday
January 22'th, starting at 17:00.

Short impact for the WiFi services (eduroam and NOMAD) and NOMAD
on Ethernet can be expected.

Maintenance successfully completed. However, it do not solve the hardware/
software issue, so additional maintenance can be expected in the future.

Imorgon onsdag 24 januari kommer vi produktionssätta nya versioner av både CPL och research.chalmers.se, mellan 10?12.
Den stora förändringen är att all hantering av forskningspublikationer flyttas från CPL till Research.
Vi förväntar oss inga större avbrott.

Wednesday, January 24th there will be new versions of CPL and research.chalmers.se deployed, between 10?12.
The big change is that all research publications now will be handled in Research instead of CPL.
We don?t expect any major disruptions.

This maintenance is now completed.

When the system was removed and added to the eduroam service, most users
had to reauthenticate - usually done automatically be the client system - so
we did have some service impact.

We've for some time experienced problems with the infrastructure used by WiFi
at Chalmers (eduroam and NOMAD) and NOMAD on ethernet.

At request from the vendor, we must upgrade the software in this equipment.
This will be done today (January 29th) after 17:00.

Service impact is expected. The services may be down for several minutes.

It is likely that the software upgrade yesterday in components in our WiFi
infrastructure solved our hardware/software problem.

We need to do a hopefully final maintenance to make this fix complete.
This will be done on Thursdag, February 1'th, after 17:00.

Some service impact is expected, but shorter than last time.
Affected services are WiFi (eduroam and NOMAD) and NOMAD on ethernet.

On Thursday February 8th we will upgrade one of our authentication
backends for eduroam and NOMAD.

We do not expect any service impact, but redundancy will be lost during the
maintenance.

We believe we can avoid the reauthentication users had to do when we upgraded
another server on January 24th.
