Scheduled Maintenance — Kista Datacenter Migration
February 21 – March 8, 2026
We are live-migrating all VMs from our Kista datacenter (DC1) to Älvsjö (DC2) as Kista is being decommissioned. Both datacenters share a dedicated 100G L2 link, so no service interruption or degradation is expected.
Please keep an eye on your dashboard at cloud.hostup.se for any maintenance reboot notifications.
Update March 3
10 out of 15 servers have been moved successfully — zero downtime, zero reboots so far.
Reboot required for Ryzen 9950X and EPYC Genoa 9654 plans: these 2 servers cannot be live-migrated because we don't have matching CPU hardware in Älvsjö for the host-cpu passthrough flag. VMs on these nodes need a single restart (stop + boot — just like any restart via the control panel). No other action is needed.
- EPYC Genoa 9654: once set to the "AMD EPYC Milan" CPU type, VMs can be live-migrated back without issues.
- Ryzen 9950X: a second restart will be needed the same day to migrate the VM back to its node, because the base-frequency difference is too large and would cause a TSC clock drift issue.
Automated health checks running every 30 seconds. Web hosting monitors use test WordPress sites — brief unavailability (1-2 min) may occur during auto-updates.
