|Affected||everyone trying to resolve *.science.ru.nl *.astro.ru.nl etc.|
DNS-servers for ru.nl did not serve information about subdomains such as science.ru.nl. Thus no DNS-name will resolve to an IP address at FNWI. A workaround is to use as DNS servers: 18.104.22.168 en 22.214.171.124. If you try to connect to a service for the first time after ca 11:15, you’ll get an error like: “No such domain” or “Cannot resolve”. Restarting RU DNS servers at 12:45 may have fixed the problem. Without a real explanation, the problem went away after a few hours.
