I have been thinking more about this. Here we have a number of people
with different hardware, different browsers, ISPs and operating
systems, who suddenly experienced the same problem in accessing APOD,
all about the same time, which would indicate that something outside
their control has changed. We cannot get past some server on the NASA
network yet the vast majority of people have had no trouble at all.
Something somewhere closer to NASA than to us has changed for the
worse for a handful of users. It might be something which requires us
to make some change at our end, but who knows? Is it a routing
problem?
antwrp.gsfc.nasa.gov and apod.nasa.gov both resolve to 129.164.179.22.
traceroute gets as far as cn-fw-x.gsfc.nasa.gov => 198.119.58.6.
dig reports NXDOMAIN (non-existent domain) on both addresses, possibly
because the domains are private? ping fails but it succeeds for the
server one hop back, 4.69.149.3. Tried traceroute again and ended up
on a different server:
Code: Select all
16 * * cne-gw-sip.gsfc.nasa.gov (198.119.56.66) 94.879 ms
so it looks like they have a server farm there and all of them hanging on my requests.
