Cyon DNS outage

now both servers respond in acceptable time again. We’ll keep an eye on it

since about 10-15min the issue is active again. Their two NS are responding very slow to DNS queries

our tests show that cyon.ch seems to have fixed the issue. Their authorative nameserver are reachable again and do respond properly to queries

Currently none of the authoritative name servers operated by Cyon are responding to queries. This may result in mail delivered from Cyon servers to be falsely classified as spam as reverse DNS of Cyon mailserver IPs cannot be resolved. Mail from domains using Cyon DNS hosting may be delayed if neither MX nor A record can be resolved. Mail to Cyon customers is delayed as our servers have no way of knowing where to deliver those messages.
