Skyscanner may be the worst ad, so have a look which ad is after the first post if it loads slower than usual, but it's fine on mine and other browsers, and the servers not suffering any slowdown, I have a 3rd party monitor.
Someone on my Racing Forum said he finds it loads quicker on Chrome for him, but others say it is fine on whatever browser. I use IE9, and Rayna Chrome.
You can also find firewalls slowdown your internet.
