I can't resolve anything for kernel.org from Verizon's 3G network, or

HE in California. I'm using HE's nameservers, with Google's as a backup.
Neither of them have any records. Anyone know what's up?


Strange one.

Also fails with my ISP (BE*There in the UK), but, org. nameservers have it
fine:

$ dig kernel.org @c0.org.afilias-nst.info.

From here (near Chicago), ns.vger.kernel.org is reporting that
ns7.kernel.org and ns.vger.kernel.org are the authorative servers for
kernel.org.  But the .org roots are claiming ns.vger.kernel.org and
ns4.kernel.org are the authorative servers to use.

ns4.kernel.org is not accessable from here via IPv4 or IPv6.

ns7.kernel.org seems to be giving out sensible answers.

That will cause strange issues across the Internet until the roots match
what ns.vger.kernel.org shows or ns4.kernel.org comes back online.
