I just got word of this problem now; it appears to be a DNS issue, however
the DNS configuration of the Trinity web services has not been touched in
several months, leading me to suspect upstream equipment and/or caches. 
Curiously, only the ppa.quickbuild.pearsoncomputing.net DNS entry is down;
all other DNS entries appear to be functioning normally.  Also, "nslookup
ppa2.quickbuild.pearsoncomputing.net pearsoncomputing.net" returns proper
information, whereas "nslookup ppa2.quickbuild.pearsoncomputing.net"
fails.

It is very late here so I cannot look into the problem tonight, but I will
see what I can do tomorrow.
