We dropped SSLv2 and SSLv3 and some TLS algorithms. This dropped a lot
of clients who were already 'end of lifed' from checking in. [They may
still be trying but handshake not happening etc.]
This dropped measurement Fedora 12, 13, 14, and 15 by about 95%
overnight. For whatever reason, did not affect F11 and earlier, or
later.
There's no particular reason to expect that F12-F15 do anything but
follow the very slow long tail decline we see in releases before and
after that, and so for reports where I'm showing a pretty overall
picture — or when trying to answer questions like "how many legacy
systems vs. current or recent releases"? I usually use a projected
value.
I don't have an excellent explanation for the drop we saw *this*
summer, except the observation (from another dataset) that it seems to
be mostly a drop in i686 while x86_64 is still growing.
