Slow Websites

[#1]

This isn't meant to be a dig at PlusNet but I'm just curious why Ebay and Digital Spy are so slow for me? Does anyone else get that? Digital Spy is the worse. It's so slow I often just give up trying to navigate it.
I hop between Google DNS and OpenDNS but experience the same phenomenon with both along with PlusNet DNS. Speeds below.

Just tried both websites and they both work fine for me

Very strange.

fwiw, I've also frequently observed long delay when trying to access eBay for the first time during a session on number of occasions all this week. If I stop the browser session and retry ebay, it usually let's me in.    Once I'm on ebay, navigation is fine.   I just assumed it may be an eBay site issue.
I'm using DNS: primary: 212.159.6.10 (plusnet) and secondary: 8.8.8.8
currently connected to pcl-ag03 gateway, but I don't think this is a factor as I was using a different gateway earlier this week and still had issues connecting to eBay.
Update: I think I may have found a possible reason for the issues I have been seeing with eBay.  Turns out it might be something to do with Adblock extension which I use in chrome web browser for windows.
