[Datastream #CZV-308644]: Fwd: NEXRAD on AWS outage

Hi Chris,

Thanks. The metrics you sent will help, if nothing else, me knowing another 
time I need to backfill into the archive.

We're not much closer to understanding the problem, as all our instances in 
us-east-1 show the sporadic network issues maintaining data flow from the 
LDM--but not severe enough network issues to completely bring down 
connectivity. Based on testing yesterday, these problems are not shared by 
us-west-2. We are looking, then, at spinning up a full new instance in another 
region to serve as a workaround (it's not optimal since the data are uploading 
to S3 in us-east-1).

In the meanwhile, it looks like data continue to flow fine for now.
