On Monday evening, 2020-04-06, we will upgrade the firmware on our data center switches in zone LPG1 (Lupfig). During this maintenance work you may experience short periods of packet loss (up to one minute) or higher RTTs for connections from and towards the Internet and between virtual servers (even when using the private network interface), as well as short delays for I/O operations to SSD/Bulk volumes and our Object Storage in that specific zone.

Date / Time
Monday, 2020-04-06, 23:00 to Tuesday, 2020-04-07, 01:00 (CEST)

Expected Impact
Short periods of packet loss (up to one minute) or higher RTTs for connections towards the Internet and between virtual servers, as well as short I/O delays.

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