Hi All, apologies for the late reply, I've been away on holiday this week and tried to stay offline, so only just catching up. It looks as though there has been some sort of event this week; the server has seen a massive increase in http requests but traffic and bandwidth have remained stable. It's possible that it was some sort of attack but I'm still investigating. The server isn't quite back to normal but nothing like the level seen in the first half of last week. I'm keeping my eye on it for now and will report back. Thanks all for reporting this incident and apologies for the inconvenience.
