Thanks, the errors seem to have gone away.
Just to be clear this is to update our local site mirror (serving about
600 machine). We only have one server connecting to you - making 4
connections one after the other as we pull over bits for sl3,sl4,sl5,sl6 -
we don't mirror the entire trees just the bits we think we need...
In fact it does already have a random delay in it though since that is
just the time taken to process various local repos it may not vary that
much on a typical day.
How large do you suggest making the random variation?
We currently run the scripts at about 03:37 (GMT0BST), so I suppose that
may correspond to a busy time elsewhere in the world - should we move it
to a different time?
