I've been observing some intermittent connection issues to the NL resolver. The last time this took place was between March 9th at 00:29 AM till 02:40 AM. During this time period, the server itself was up but the webinterface was not responding to requests. I am unsure whether or not DNS requests are also affected, hence I have put more logging in place. I will be monitoring this over the course of this weekend.

Currently the webinterface is unreachable again. I've identified the issue and will work on resolving it asap. DNS service is unaffected and remains operational.

The changes I made seem to have resolved the issue, therefore I am closing this incident.
