[LDM #GUQ-669331]: Both Radar and Satellite feeds stopped downloading abruptly



John,

No worries.

I agree.

It still could be campus-wide congestion.

That would be consistent with everything we've seen.

Can't you use ntpd(8)? If not, then why? I've never heard of a site not being 
able to use ntpd(8).

> 4. The bandwidth of the AT&T network pipe is also 10Gbs.

Good. That will suffice.

That's exactly the trace we would expect to see for a site that's receiving the 
products with little latency but who's clock is off.

Show this new information to your network administrator and request that they 
fix the problem.
