[OSM-talk] Old data being cached too long

[Matias D'Ambrosio]

 I thought there were some errors with OSM but today visiting a friend we used 
OSM and mapnik was looking just fine, no tiles were old, while at home I get 
a patchwork of new and old, and I have to hit reload a bunch of times to get 
the right one. It's not my cache, btw, I did check for that :-) (Besides, I 
use multiple browsers and they all looked exactly the same.)
 There is the small chance that OSM is doing something wrong that might cause 
this, but in all likelihood it's my ISP doing business as usual. I know they 
use a transparent proxy, which is quite opaque as this case shows, but not 
being a proxy-knowledgeable person, I don't know exactly what they broke in 
theirs. I see some tiles that are at least two render-cycles old (more than a 
week and a half), and reloading each tile manually is quite annoying, plus 
it's one, if not *the*, largest ISP in Argentina. Could anyone tell me the 
right keywords? What bits to flip? Tomorrow is saturday and I'll be doing 
some work with plenty of dead time for me to call their toll-free number and 
see if I can get someone who can talk beyond the scripted responses (I talked 
with one such person a few years ago), who knows, they might fix it if I 
provide them with the right info.
