Thursday 28.10. at 21:05 we noticed unavailability of some .cz domains in our administration. The error affected those domains that use the older NSSET NSS: GLOBE-SGLO000001: 1.

The nameservers in this NSSET where changed due to a technical issue, which caused unavailability of the affected domains.

We resolved the issue within one hour. The fix took effect in most domains within the next hour, depending on the recovery rate of DNS resolvers.

After a prompt repair, we start working on our processes so that such a situation cannot happen again. We apologize for any inconvenience.
