Repeat Issue: Bookmine.co Unreachable – Routing Failure in ibone Seattle Backbone

@XfinitySupport I am unable to access bookmine.co on my Xfinity connection, even though the site works fine on other ISPs and even for other Xfinity users just 15 minutes away. Bookmine has already whitelisted my IP, so it is not blocked on the site’s end. Advanced Security is turned OFF on my account, and a previous ticket (IH265388373) confirmed there is no block. Traceroute shows the connection failing inside Comcast’s ibone backbone in Seattle (it times out immediately after hop 7). This exact issue occurred previously, and after escalation it was corrected by Comcast, but it has now returned. I am requesting that this be escalated again to the network routing/peering team for review. Please note this is not a device issue, not an Advanced Security issue, and not a problem with the website itself.
