It seems that your servers are blocking some of our IP addresses. Is it possible to understand why or, at least, to unblock IP subnet 31.187.78.0/24 ?
If not, is it possible to at least unblock IPs:
31.187.78.23
31.187.78.31
Is it also possible to get more information about WHY this block happened ? Those IPs have been checked with Symantec IP reputation service at:
http://ipremoval.sms.symantec.com/lookup/
and have been found not to have a bad reputation so WHY are they being blocked ?
Thanks.
