Art,

It looks like your machine experienced a 1200 second interuption.

Your HDS feed shows the jump up, and has now gone back to normal:

The same 1200 second jump occurs in your NNEXRAD and NMC2 feeds from
SSEC and Thelma respectively:

http://www.unidata.ucar.edu/staff/chiz/latency/stats/NMC2_ldm.meteo.psu.edu.gif

You can view all your rtstats being sent here at:

The 1200 second jump does not appear in thelma's reception of NMC2 from
outside here, so it would appear that it is on your end, especially since 
the jump appears in both your feed from SSEC and from here.

Since your HDS has gone back to ~0, I would look for the other feeds to begin 
to 
recover too....but they are larger and will take more time.

In the mean time, if you don't see improvement, let us know. We can keep
track of the latency graphs on this end.
