Hello,

Maybe someone can help me here:

So suddenly come the user no longer on the side <www.nrwshuttle.de>
Here is an excerpt from the live log:

2013:02:05-12:46:09 mailpub httpproxy[5843]: id="0061" severity="info" sys="SecureWeb" sub="http" name="web request blocked, reputation limit" action="block" method="GET" srcip="..." dstip="" user="" statuscode="403" cached="0" profile="REF_DefaultHTTPProfile (Default Proxy)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="6820" request="0x8440d468" url="http://www.nrwshuttle.de/" exceptions="" error="" reason="category" category="152,204" reputation="malicious" categoryname="Travel,Malicious Downloads"

What can I do, that we come back to this Site?

Best Regards Sonja
