My ISP (Yahoo Smallbusiness) is having troubles since yesterday.
As a result it has been impossible to access the website, the forum, or anything using the DNS either (this impacted miniserve.defence-force.org, but not miniserve.getmyip.com).
Apparently it's working at the moment, but well... you never know, never two without a third.
You can monitor the situation here:
