Scheduled Maintenance

[ZRH] API Server Maintenance (URL change) Sep 19, 2026 11:00-14:00 UTC

CloudSigma would like to inform you that we are planning to perform scheduled maintenance on our API server in the Zurich cloud location. The aim of the maintenance is to perform the previously announced URL change from zrh.cloudsigma.com to gva.cloudsigma.com.

IMPACT:
There will be no impact on already existing/running customers’ virtual machines, hosts, network accessibility, and/or any other running services. During the maintenance, customers will not be able to perform any calls to the API, directly or through the web interface, for about 3 hours. After the maintenance work is complete, the API will respond to calls on its new domain name, and zrh.cloudsigma.com both, until the 22nd of October 2026.

As it was mentioned in our initial announcement about the upcoming domain change, we highly recommend that you update your bookmarks, automations and API calls to use the new domain.

While it is important for CloudSigma to perform maintenance such as this to ensure the quality of our services, we do everything possible to minimize any inconvenience for our customers. We appreciate your patience and welcome any feedback.
