What's your evidence that this is related to c.root-servers.net serving a stale version of the root zone? If you can get the correct IP address for a site out of the DNS but can't reach the site, it's not a DNS problem, and not a problem with the root DNS servers. This is likely correlated only in time with the c.root-servers.net issue. That said, your difficulty reaching indilib.org may be related to the Cogent-TATA peering dispute or one of Cogent's other peering disputes - from where I sit, a traceroute to indilib.org goes through cogent's network. But that's not what this submission is about.
