Network Maintenance: Firmware Major Upgrade on Switches in Zone RMA1 from 2023-04-12 22:00 CEST to 2023-04-13 01:00 CEST

Maintenance has successfully been completed

On Wednesday evening, 2023-04-12, we will upgrade the firmware on our data center switches in zone RMA1 (Rümlang) to a new major version. During this maintenance work you may experience short periods of packet loss (we measured around one second of packet loss in our lab) 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
Wednesday, 2023-04-12, 22:00 to Thursday, 2023-04-13, 01:00 (CEST)

Expected Impact
Short periods of packet loss (up to several seconds) 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.
