[AG-TECH] Ja.net Peers file usage

Dear All,

	It has been reported to us that the Peers file being hosting by Ja.net 
is being very heavily hit (100's of times a second).  As far we can tell 
this is not by either the UK's servers that are running the RegistryPeer 
and a quick check shows that clients only access it when manually 
requested (eg purge bridge cache).

	Does anyone have any suggestions? Could a change of someone's 
configuration when ANL switched have caused this? Unfortunately we have 
not got access to the logs files to investigate where these hits are 
coming from.
