Hostpoint DNS outage

Issue was resolved by Hostpoint. We can confirm DNS resolution is working reliably again.

Currently only one out of three authoritative name servers operated by Hostpoint is responding to queries. This may result in mail delivered from Hostpoint servers to be falsely classified as spam as reverse DNS of Hostpoint mailserver IPs cannot always be resolved. Mail from domains using Hostpoint DNS hosting may be delayed if neither MX nor A record can be resolved.
Hostpoint acknowledged a service disruption, see https://www.hostpoint-status.com/
