Core Network: Major Software Upgrade from 2023-12-11 21:00 CET to 2023-12-11 23:03 CET

Maintenance has been completed successfully.

Maintenance Work
Now that the vendor has identified the root cause of the network instability during the last upgrade attempt as a bug in their routing software, we will upgrade our core network in LPG1 (Lupfig) to a patched software release. 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.ch will not be affected by this maintenance work.

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.
