Right. It was mod_security's suspicious User-Agent rule that was triggering
the firewall block.

[Mon May 13 23:27:28 2013] [error] [client] ModSecurity:
Access denied with code 403 (phase 2). Match of "rx (^w3c-|systran\\\\))"
against "REQUEST_HEADERS:User-Agent" required. [file
"/usr/local/apache/conf/modsec_rules/20_asl_useragents.conf"] [line "130"]
[id "330039"] [rev "4"] [msg "Atomicorp.com UNSUPPORTED DELAYED Rules:
Suspicious Unusual User Agent (libwww-perl).  Disable this rule if you use
libwww-perl. "] [severity "CRITICAL"] [hostname "centos.hostingxtreme.com"]
[uri "/6.3/os/i386/repodata/repomd.xml"] [unique_id

This was the only IP blocked for this subdomain, so legitimate users should
not be getting affected. I have disabled that rule for this subdomain.

As far as the slowdown is concerned, we do not have any block based on DNS
/ rDNS / region / location etc. In all the test tools etc, the DNS does not
seem to be the problem.

Wait 83.19%
Connect 8.53%
SSL 6.04%
DNS 2.23%
Receive 0.01%
Send 0.00%

Any other suggestions welcome.
