Apologies for this - it was happening to me earlier this week but as no-one had mentioned it on here, I assumed it was just me.
Curiously if I use Safari on my MacBook Pro I get the "Server not responding" thing intermittently, but if I use Chome on the same machine, I literally never get it.
I've not made any changes at all recently, so it's a bit of a puzzle. I've had a little poke around and can't see anything obviously amiss, but I'll keep looking as I know it's frustrating.
