All,
I just now opened my first emails related to the "outage." I notice no
announcements from the TOC during the period.
I saw notes about the new architecture is not robust enough, but
confusion on what the architecture is. Please see a related article in
our NEXRAD NOW available at: http://www.roc.noaa.gov/WSR88D/, page 6.
Please tell me more about alternative architectures that were proposed,
I am not sure I saw them. Does anyone have stats on the
pre-architecture vs post-architecture Level II reliability and
latencies? How about the times of the outage?
Tim
?

Tim will almost certainly get the message...
FOr the record, though, unless things have changed, all data now goes to
redundant servers at SRH and MAX gigapop (or perhaps TOC), from whence
it's distributed to OU, Purdue, ECREN, and from THOSE to downstream
customers.
I've suggested strongly to NWS OCIO that this was not a robust network
design but I probably wasn't circumspect enough... they didn't want to
look at alternatives.
I'm still seeing significant latency in completion of the data. I'm
going to try to ascertain where we're currently feeding (OU is my BEST
source but not my only one) and see if there's an upstream ntp problem
or bandwidth contention problem.

It just started flowing via TAMU. Huh. Odd.
