Perfect. This is what I was asking about in the call.<br>
<br>
<br>
> which would all resolve to earthquake.usgs.gov<br>
<br>
You mean all the ehpN-earthquake servers handle requests for <br>
earthquake.usgs.gov and origin-earthquake.usgs.gov, right?<br>
<br>
<br>
<br>
I think our origin lag problems with Akamai are because we use(d) <br>
ehpwebback.cr.usgs.gov as our origin server name, which is a round- <br>
robin DNS name instead of a wellness-checked DNS name.<br>
<br>
<br>
<br>
Thanks,<br>
<br>
