= Y27 - Network migration to NAC =

 * Building Y27 will be migrated to a new network setup on 01.11.2023 - '''the whole day'''.
 * Our server room is inside the building, so '''all services will be down''' as well.
 * During the whole day, the institute will be offline, even '''WIFI and local desktops''' will have outages.
 * It is recommended on this day '''not to work''', neither '''on-site''' nor '''remote''' with I-MATH IT services.
 * All I-MATH services will be inaccessible: Websites, Mail, Thinlinc, Compute, ...
   * Email sender from outside I-MATH might receive a mailer daemon error about 'late delivery', but all mails should be delivered after the building is online again.
   * Computations on our compute servers '''will continue to run''', but won't be accesible during the migration. If the programs needs network acces (license server, internet) they might have problems.
 * !SeminarLive Streaming / Recording won't work in Y27.
 * Beamers in Y27 have to be controlled by remote.

== Action ==

 * Thinlinc Terminals and printers will be migrated by I-MATH IT Support .

 * '''Users''' with Desktops or Notebooks who uses LAN (WLAN is not affected) have to activate the network authentication (see UZH-NAC-Infos-Users-V1.3-EN.pdf) with their '''personal credentials'''.

== Roadmap ==

 * NAC Migration starts at 07:00. All network (LAN & WLAN) will be switched off.
 * We expect that the server room will be back online around 11:00. Depending on the problems, hopefully most services will be back online again (but not the Terminals in the offices).
 * '''Update''': We'll install OS Updates in the morning and reboot all thinlinc servers.
 * Around 16:00 we expect that the Thinlinc Terminals in Y27 are also back online again.

== FAQ ==

 * Q: The Terminal in my office shows no login window.

   * A: Please power off/on or press a key (if this is offered). The first boot might take some time. If this does not help, contact I-MATH IT Support.

 * Q: My Desktop / Laptop has no internet. 

   * A: WLAN: wait until the WLAN is back online.
