Are we talking about the balloon AE0SS-11 yesterday that I listed the URLs for,
or did you also fly a balloon with the callsign K0ANI-11 yesterday?

If so, none of those packets made it to findU.com. I also checked with APRSworld
to make sure it isn't a problem with findU, and the last packet Jim has from
K0ANI-11 is October 15, even earlier than findU has. Unless Jim and I have
exactly the same bug, which is quite unlikely, no data from K0ANI-11 made it to
the APRS IS yesterday!

No, findU ignores timestamps on the packets, it uses the time a packet is
received from the APRS IS. These packets were indeed received 1394 hours ago!
Did K0ANI-11 fly October 16?

You misunderstand, the reason is, if indeed K0ANI-11 flew yesterday, none of its
data made it to the APRS-IS, and therefore no data is archived on findU.com!
