Failed To Download Update / Could not contact primary server

cminus

This morning, the Sophos icon displayed an X in the center of the shield but wasn't grayed out, and the first entry on the menu was a grayed out "Failed To Download Update".  Choosing "Update Now" causes the Sophos AutoUpdate Status window to open, briefly display the "downloading" bar, then end with "Could not contact primary server" and "Authentication Error" followed by the date and time.  Looking into the console, I see that early this morning there were a number of messages regarding Sophos, almost all of them along the following lines: "3/19/15 7:28:22.685 AM SophosSXLD[137]: [SMESXLInterface.m:437] no DNS addresses found", and similar messages appear to go back to at least March 13.

Is there a problem with the Sophos server, and if so what's the prognosis?  Or is it something with my computer, and if so what should I do?  I'm running Sophos Home Edition 9.2.4 (Threat detection engine 3.58.1, Threat data 5.12) on a Mac running OSX 10.9.5.

    Well, I am a bit OCD so I didn't just dig for the dci host, but for all three names originally given by the Sophos technical director fellow. Output below was obtained approximately 3:10pm CDT on 19 Mar 2015...
