Nah, there's definitely something else going on. If I look at
https://b.tile.openstreetmap.org/19/261975/174355.png (last rendered at Mon
Feb 27 08:55:42 2017 according to /status), then when it's served via
saphira.openstreetmap.org:3128 I get the old tile, with etag
"6463a418be94b7515745cdb9ed2071d3"
but when it's served via ridgeback.openstreetmap.org:3128 I get the new
tile, etag "038cdf917e46ae930f63678d8652b627".

One way to get the new tile (from ridgeback) appears to be to force refresh
on another zoom level to clear cache, then zoom in with mousewheel (so that
the request gets issued via js, I guess). I'll stop playing with it now to
avoid adding load, but I'd guess that maybe saphira needs its cache
cleaning out a bit?

Cheers, Ed
