E-root instance in San Francisco servfails?

[Stephane Bortzmeyer]

The instance p03.sfo.eroot (San Francisco, I guess) returns SERVFAIL
for, apparently, every request.

I wrote to NASA through their contact form
<https://e.root-servers.org/contact> on 17 june, but no
reply. The problem disappeared but reappeared today.

You can see the problem on RIPE Atlas test #110654770
<https://atlas.ripe.net/measurements/110654770/> or in this DNSviz
test <https://atlas.ripe.net/measurements/110654770/r>.

Any idea?
