<br>
<br><font size=2 face="sans-serif">Nicely done! I have a few comments
to share.</font>
<br>
<br><font size=2 face="sans-serif">Most notably, I still don't quite get
how you can avoid the need to replicate between the two Master servers?
Sounds like you're operating the two nodes separately and assuming
they will build identical pages. Are there realistic examples where
this strategy might fail, and for whatever reason, you end up with contrasting
content on the two nodes? </font>

<br>
<br><font size=3>The EHP Web Team has been researching and discussing the
next evolution of our Web System Architecture for over a year now, and
we have finally created a document with our proposed configuration. This
system architecture is forward-looking and extensible to include more hardware
if needed in the future, and other systems such as the Earthquake Notification
Service, ShakeMap, PAGER, etc.</font>
<br>
<br><font size=3>The growing complexity and volume of our website, as well
as the popularity (approx. 28 million page-views per week), and the requirement
for guaranteed availability calls for a more robust and reliable system
than we have now, and we believe that this proposed solution will serve
the needs for the foreseeable future.</font>
<br>
<br><font size=3>The authors and consultants for this architecture include
Eric Martinez, Jeremy Fee, Ray Buland, Chris Bidwell, Stan Schwarz, Judy
Tegeler, and many other product providers.</font>
<br>
<br><font size=3>Please provide us with feedback and comments by October
31 by replying to this email. You may reply to the EHPWeb email list
or just to me.</font>
<br>
<br><font size=3>Thanks!</font>
