F.ROOT-SERVERS.NET moved to Beijing?

I happened to notice the following at three separate sites around
the US and one site in Europe:

$ dig +short +norec @F.ROOT-SERVERS.NET HOSTNAME.BIND CHAOS TXT
"pek2a.f.root-servers.org"

and:

$ dig +short +norec @F.ROOT-SERVERS.NET HOSTNAME.BIND CHAOS TXT
"pek2b.f.root-servers.org"

After running a couple of traceroutes it appears that he.net has a
route for F's anycast IPv6 address (2001:500:2f::f) towards Beijing.
According to https://www.isc.org/community/f-root/sites the Beijing
node should be a "Local Node" (without IPv6 but I suppose the list
is not up to date).

I believe this means that a lot of DNS queries from IPv6 enabled
sites in US and other countries are going to Beijing. I wonder if
this is intentional? Chinese government (CNNIC) seems to be in the
path.

All my sites seem to have he.net somewhere in the IPv6 connectivity
path. I wonder if this is specific to he.net or more wide-spread
routing anomaly?

I have notified he.net NOC and F-root @ ISC.
