One bizzare thing which happens sometimes is ICMP packet blocking and this can break MTU negotiation. It is supposed to be very rare, but the reality is that one fairly often comes across a website which doesn’t load, or runs extremely slowly. A useful check is this.
Some people, who don’t want to be tracked by the National Security Agency 
access the internet via a VPN. These VPNs are widely marketed. They often break connections too, for reasons unknown but possibly connected to MTU. I have one right here (for experimenting; my internet browsing is nothing special 
) which clearly fails for MTU reasons, but it’s not obvious why.
It would be interesting to hear if anyone has issues described. There is no IP based blocking on EuroGA. I know a certain UK GA site blocked everything outside “western” Europe and the US, due to most spammers coming from outside, but that policy would not work today because only the other day we had the usual fake-passport case from an IP in the UK. I asked why block access from e.g. Czech Rep and the chief mod’s reply was that it is worth it for the reduced hassle.
There is only this but I doubt they do IP blocking.
That’s an O2 WiFi IP address FWIW.
46.233.78.194 …
That’s a local subnet. What does it say when you go to http://myip.dk
Corrected. Admin informed for the IP
What is the IP you are on when that happens?

Just waiting forever to load euroga. Of course, never loads.
Nothing really happens. Just blank.
If you need any testing let me know.
I’ve found that e.g. Virgin Trains WiFi in the UK goes out via an Amazon AWS IP. Which is often blocked by site operators because usually 99 % of AWS traffic is from dodgy bots and SEO crawlers.
What happens when you try? Do you get some kind of message? A screenshot is golden in trying to diagnose these kind of issues, but failing that, a description would be good.
