DNS nameservers that don't forward their requests to other DNS servers, need to know some of the IP addresses of the root nameservers in order to find their way to the rest of the information. They either have this knowledge built-in or use an external file containing in initial mapping.
The "L.ROOT-SERVERS.NET" root nameserver changed IP address, and hence some updating to the hints could be useful.
For the record: this isn't an urgent update. Consider it an opportunity to verify you nameservers are up to date on patches and perhaps to learn a few bits on how the DNS system works.
