Here is today's summary of NHC computer operations:
--- Craig Mattocks


1. There have been intermittent connectivity issues to the FTPIngest  
(FTPGate) server (ftps-in1.ncep.noaa.gov) where NHC sends the surface map  
and other TAFB products. TSB Developer Matt Sardi updated the FTPIngest  
send script/configuration to timeout after several tries to make the  
connections more robust. As of last night, NCO network support was still  
working on fully resolving the underlying networking issues. If problems  
persist, TAFB forecasters should contact the SDM, who is aware of the  
situation. Update: the SDM reports the problem was due to problems with the  
operational TG FTPS server (ftps-out1a/b.ncep.noaa.gov) at NCEP, fixed at  
0127Z today. Multiple network problems (DNS, routers) ongoing across the  

2. Surface Analyst Evelyn Rivera-Acevedo had problems running the launch  
script for the 18Z Unified Surface Analysis (USA). TSB Web Developer Dave  
Zelinsky determined that the problem was at NCEP, where receiving servers  
were hanging up on attempted connections and NCO is investigating (see Item  
1 above). Dave suggested that TAFB watch launch scripts that may hang up on  
attempted connections, and use a Ctrl-C to skip hung processes and continue  
on to the next connection written in script. No problems were encountered  
with the launch of the 00Z map. TSB Developer Matt Sardi called TAFB  
forecasters multiple times to monitor the situation.

Other items:
1. There is an outage of ASCAT-A scatterometer data from 0819-1406Z today  
due to a plane maneuver (orbital inclination change) by the European Space  
Agency's Metop-A polar orbiting satellite.

2. Beginning at 1055Z yesterday, the GDAS (global data assimilation  
system), NAM and GFS models started started alerting due to low ACARS  
(aircraft) data counts, caused by power maintenance and firewall issues at  
the FAA's Weather Message Switching Center Replacement System (WMSCR) in  
Salt Lake City, Utah.
