Update 27th Aug 2019: Check My DNS and dev.dns-oarc.net is back online, other services such as buildbot etc will be brought up tomorrow (28th Aug). If your still being redirected to this page you need to wait for DNS to propagate.
Our development server dev.dns-oarc.net will be down for maintenance starting Monday 26th August, expected downtime is around 4 days but might be extended. This downtime will affect Check My DNS also.
Our Debian package server at pkg.dns-oarc.net is hosted on the development server, prior to this maintenance period it will be moved to our main web server which hosts www.dns-oarc.net.
