oops, yes, typo, I'm getting old, could not keep the 69 mm in head from page 1 of this thread (Dougies post)

PS:... sorry, another typo or two in your name! Really getting old... ;-)
Kind regards

Yeah, the Zero doesn't really work that well for this. It had stopped working after a couple days so I repowered it and sshed to it. Now I've been waiting like 10 minutes for the first map to appear.

It's running nginx so I went looking for comparisons between nginx and lighttpd, found this one

Eventually I did get a map. It's overloaded, I see frequent error overlays that it's not getting data fast enough, not many planes.

Hi ab1jx,

I always use a desktop to view the output remotely - so it is doing all the javascript processing. I might get chance to set up a 3B in place of the zero with everything else the same and see how that affects the stats (although this is probably not the best weekend for trying to compare against previous data - being Eater Sunday followed by a UK statutory holiday). However, by the weekend air traffic should eb back to normal.
