Hello,
As part of our upcoming failover exercise, we have updated ehpbackup
to provide a true secondary master webserver for our primary master
webserver ehpmaster. One change was to enable the periodic
replication of content from ehpbackup, the same as ehpmaster. This
replication led to out of date content in several cases because it was
not up to date on ehpbackup.
BOTH ehpmaster AND ehpbackup replicate content to the public web
servers. This provides a redundant path for content to be delivered
to the public. If you rely on this replication from ehpmaster, you
MUST also push that same content to ehpbackup. If you only push
content to one of the master servers, and that server fails, your
content may not reach the public. Additionally, if your content is
not up to date on BOTH master web servers, out of date content may
reach the public web site.
Please contact Chris Bidwell <cbidwell at usgs.gov> if you are unable to
connect to ehpbackup for this purpose.
Thanks,
Jeremy
