Certainly not, your resolver removes it automatically from the list of authoritative servers for the zone. Also, named will add it right back to the in-memory cache (the one that matters) since it will reach out to one of the hints servers to find the up to date list of root servers. The hints file is just a hint of how to find the roots, not an absolute list of root servers. In any case, this was only(!) a 9.5 hour outage (2016-04-14 03:00-12:30 UTC). Any kind of local manual configuration change would have been an inappropriate response.

Zero impact (that's why you must have several name servers for a zone, idm.net.lb has only two, which is light). ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Do you think it is better to remove it from named.root? Is there any impact on the DNS resolving ?
