Seems to be some DNS resolver and network blocking, possibly only outside the US, to maia.usno.navy.mil and www.usno.navy.mil; interactive web browser access to tycho.usno.navy.mil and aa.usno.navy.mil mostly work, but web browser ftp access does not, and non web browser resolution and access do not, e.g. host or wget; however everything resolves and is accessible form the browser and command line from toshi.nofs.navy.mil. Some other previous reports back this up, but there were no followups to say whether issues were temporary and cleared up, or persisted and were permanent. It may be possible that lookups or accesses may be rate limited to deter intrusions, or entries may have expired because they may be offline for July 4 thru the weekend, or sites may be blocked due to lack of monitoring staff or funding for non-defense services. -- Take care.
