I'm using the timeseries service (via obspy) to download BH data one day at
a time, and I'm getting a lot of timeouts. I'm trapping 404 not founds, but
many requests are just timing out. Retrying usually doesn't help. I changed
the timeout parameter from 10 to 30 seconds with no apparent difference.
Under what conditions does the service time out instead of sending a 404?
Do I need to run a timeout setting longer than 30 seconds?
Thanks!

Hi John,
How long are the connections idle before you get a timeout? Our network equipment will drop idle connections after about 4-5 minutes of inactivity. Other than that we do not impose any sort of timeout or return an error status for a timeout condition from the services themselves. In most cases we find that default timeouts in client software are shorter than 4-5 minutes and that's usually what folks run into.
Also, can you send an example of the request you are submitting so we can give it a go?
thanks,
Chad

Hi, Chad. The obspy client defaults to 10 seconds. I was getting timeouts
with 10 seconds; I increased it to 30 seconds without it helping much. I
just switched to 120 seconds and that seems to be better.
A typical request would be (timeseries service) CI PDM -- BHN from
2008-01-29T23:45:00 to 2008-01-31T00:15:00 , correct, autolimits,
units=VEL, demean. At timeout = 10 seconds this times out repeatedly.
Thanks!

Hi John,
Thanks for the details. I confirm that a request with those parameters is taking about a minute. While those are longish segments of data, they are still not too big for that king of processing. I'm a bit surprised these are not returning quicker. We'll take a look to see if something is gumming up the works, likely after the holiday break.
cheers,
Chad
