Unscheduled:

• May 27th: The link flap was possibly caused by an issue on the stretch Karlstad-Trollhättan, but the actual cause for the flap could not be found. The link has been stable so we will now close this case.

• May 24th: A synchronization failure on the transmission card in Karlstad caused an outage on the green link to KAU. The reboot of the transmission card restored the traffic.
• May 22nd: A faulty card in our DWDM equipment in Karlstad causing outage on the green network was replaced

Scheduled:
