Ticket Description:	Scheduled Scheduled maintenance PoP KR (30.08.2023)
Scheduled Starttime:	2023-08-30 10:00:00	Scheduled Endtime:	2023-08-30 11:30:00

Problem Description:

We need to replace malfunctioning equipment in our PoP Kreuzlingen. At the moment traffic is still running through it but changes to the system have become impossible.

The maintenance will interrupt our north eastern ring, so the PoPs along it and some optical links through it will temporarily lose their redundant routes, as listed below.

Affected:

From 2023-08-30 10:00 until 2023-08-30 11:30
Impact: no more redundancy
Service: network access
Sites: BELWUE, OST-SG, PHTG, UNISG

Impact: no more redundancy
Service: P2P/OPN
Sites: BELWUE-KIT-CE, EmpaEawag-SGE, L2VPN-OST-SG, OST-Waldau-bu1-go2, OST-Waldau-bu2-fhsg2, PSIE-CSCSBT

Actions:

The unresponsive part has been replaced. The other one, with only minor issues, is still installed, as we didn't have enough spares on hand. It will be addressed later in a separate maintenance. For now the system is stable, and redundancies are restored.
