<DIV>Eric,</DIV>
<DIV> </DIV>
<DIV>As far as latency goes, I have noticed that events do not show up in the
feeds until about a half hour later i.e. below are the last few events that I
captured from the last hour and last day feeds just today. I also noticed
that an event that gets posted in the past hour feed does not stay there the
full hour. It appears to get deleted after about half an hour. If it
is any help, I have set up a test page <A
title=http://ucweather.org/recenteqtst.php
href="http://ucweather.org/recenteqtst.php">http://ucweather.org/recenteqtst.php</A>
that shows the posted time and description from past hour and past day feeds
using a parser with no special formatting and the cache time set to zero so it
should be showing what is currently in the feeds.</DIV>
<DIV> </DIV>
<DIV>Hope that helps.</DIV>

<DIV dir=ltr>Hi Matt,
<DIV> </DIV>
<DIV>If you can reference a few recent, specific instances (event IDs) where the
event skipped the past hour feed due to latency, I'd be happy to look into it.
We have not noticed this on our end. The timely reporting of earthquake
information is important to us, so if it is a problem on our end, we would like
to fix it.</DIV>
<DIV> </DIV>

the last month or so, earthquakes are showing up later and later after they
happen. My app focuses around Oklahoma which doesn't have automatic posting
like California. (Not sure why, but i assume that's a $$ issue) Recently I've
noticed that a lot of the quakes happening in Oklahoma aren't even hitting the
"Past Hour" feed because they are taking 1+ hours to get posted. Since my app
(A twitter bot) hits the feed regularly to check for new quakes, I've found
the past hour feed to be the most efficient. (Much less data to download and
parse) However, with these quakes showing up so late, I'm missing a lot of
them. Because of this I'm probably going to have to switch to the "Past Day"
feed so i can be sure to catch everything.<BR><BR>Does anyone have any idea
why this is happening? I'm not really informed enough to know how exactly the
entire system works from the waves in ground to the json feed but i would love
if someone else more knowledgeable might be able to fill in the blanks for me.
Is this something that can be "fixed" or is it just a "that's how it is" type
of
situation?<BR><BR></DIV></DIV>_______________________________________________<BR>Realtime-feed-users
