Level3
Todd Culatta
Mark Taylor ? Customer Project Manager
Todd D?More -- Implementation Engineer
Libby McClary

Dan is updating the gs_level3 at usgs.gov 
working with Libby to make sure that the Level 3 folks are in our mail 
alias. 
Lisa Wald sent the Earthquake alias.
ACTION:  get hostnames and source servers
CDN hostnames and 
origin servers:

www.usgs.gov 
origin-www.usgs.gov


earthquake.usgs.gov
ehp1-earthquake.cr.usgs.gov
ehp2-earthquake.wr.usgs.gov
ehp3-earthquake.gps.caltech.edu
ehp4-earthquake.cr.usgs.gov

quake.usgs.gov

        ncweb-north.wr.usgs.gov
        ncweb-den.cr.usgs.gov
        ncweb-east.er.usgs.gov

neic.usgs.gov
        neic.cr.usgs.gov

For testing we need 
test-www.usgs.gov
test-earthquake.usgs.gov
        test-quake.usgs.gov
        test-neic.usgs.gov

To test the DNS split for Intranet and public users, we need to have 
another test CDN host

level3.natweb.usgs.gov that points to
level3-origin.natweb.usgs.gov

In our internal DNS .usgs.gov users will go to 
level3-origin.natweb.usgs.gov and public DNS will go to the level 3 CNAME 
(provided by Mark D?Amore @ Level 3).

*****************

Create a test hostname & content page for us to CNAME to Level 3.

Gs help dns: 
1. origin-www.usgs.gov is www.usgs.gov 
2.  supername -- test-www.usgs.gov 
Ø       Need the alias name for Level 3

CCD ? Customer Commit Date is now set to Monday 

Apache SSI ? compare incoming hostname to some text.  Edge side include is 
what we?re looking for? 
Logic based programming available 

Can have two copies of the pages that have those internal links.

Geoblocking or allowing content based on country code.

Look at the referrer header 
Whole site caching vs. object caching
Image.www.usgs.gov would house all the images that the pages needs to put 
the page together.

USGS ACTION:  Test 
Using DNS to have all ?usgs.gov? machines directed to origin-www.usgs.gov 
and public would go to www.usgs.gov
Access to USGS networks by Level 3 wellness testing and caching systems
Need to further discuss the requirement to have a known set of Level3 
servers allowed into the USGS network.  Either ip subnets or a known 
number of servers. 
Content Freshness
Default TTL is one year.  They do honor cache control headers to manage 
the TTL.
Purging content method? 
Ø       Use the portal or an API cgi that you use.

Are there query strings that generate unique per visitor parameters. 
Passing a session ID?  If yes, there is a workaround to optimize the 
caching of that content.
Portal Management
1 super user and then they will set up user accounts within USGS.
Properties = EQ, www.usgs.gov, DNS
