I took it that Clive meant there are 250 - 280,000 "visits" to the TFF website each month, if so then there are 480,000 "visits" to the FW mags each month. However, Clive has now said there are 250 - 280,000 "unique visitors" to the site which means there are nearly 280,000 different people visiting the site each month, I'm not sure that's correct but possibly is.
The total visit number is obviously MUCH higher than the unique visits number, (which is correct / independently verified) some of those uniques will make multiple visits every day to total about 70,000 actual visits per day which is near 2.2 million visits a month!
It's a serious load that's not easy to cope with at peak and the TFF AWS server solution is massive and complex ( =expensive !) as a result
