Core Network: Emergency Software Upgrade from 2026-05-11 20:00 CEST to 2026-05-11 23:00 CEST

Emergency Maintenance Work
Since we are still facing connectivity issues for certain IPv6 targets after the emergency maintenance last Friday, we have re-escalated the case with the vendor. After further consultation with the vendor, we have decided to upgrade the firmware of our core network to a new major version in another emergency maintenance window. 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
From Monday, 2026-05-11, 20:00 CEST to 23:00 CEST

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.
