Core Network: Software Update from 2026-01-19 21:00 CET to 2026-01-19 23:30 CET

Maintenance Work
Following an in-depth analysis of recent spontaneous crashes (including the incident on 2025-12-31) by the vendor of our routing software, we will update the software of our core network in LPG1 (Lupfig) to the latest minor release, that contains a fix for this specific issue. During this maintenance work you may experience short periods of packet loss (up to 1-2 minutes) or higher RTTs for connections from and towards the Internet. Connections between virtual servers at cloudscale will not be affected by this maintenance work.

Date / Time
Monday, 2026-01-19, from 21:00 CET to 23:30 CET

Expected Impact
Short periods of packet loss (up to 1-2 minutes) or higher RTTs for Internet-facing connections. Thanks to our redundant setup we do not expect any further impact on already running virtual servers.

We apologize for any inconvenience this may cause and thank you for your understanding.
