 There are numerous unresolved reports of subdomain networks failling to
 resolve the secondary sites (subdomains) after upgrading to Wordpress 3.5
 in the Wordpress.Org forum.  No one seems to be responding.

 I upgraded a network yesterday.  The primary site resolves fine but I get
 a DNS failure on a secondary site; until the upgrade this problem did not
 exist.  We had Wordpress 3.4.2 installed prior to the upgrade.  All
 plugins were up-to-date until the most recent wave of plugin updates (due
 to the release of Wordpress 3.5).  The plugins were upgraded with the
 Wordpress.

 No changes have been made to the .htaccess or wp-config.php file.  No
 changes have been made to the server's DNS or wildcard subdomain
 configuration.

 Another domain on the same hosting account, also configured for multisite
 using subdomains, continues to work fine.  That domain has NOT been
 upgraded to Wordpress 3.5.

 I am not a PHP developer and cannot recommend a fix.  This issue needs
 immediate attention.  I cannot make heads or tails of your ticket system.
