Sorry don't understand.
Tried to get wikipedia on Firefox, won't load on there, either.

Just opened this link on Chrome. https://en.wikipedia.org/wiki/Main_Page

Thanks, tried it, got "This site can't be reached".
Been talking to a friend in the UK he think problem is in Router, as I can't get "wiki" to load on any of my computers (3), or Mobile phones (2).
I'll try switching it off for a while to see if it works then.

Thanks to all for trying to help!

Works fine for me on my AIS Fibre home internet and DTAC mobile connection.

 

To bypass your router have you tried turning off the Wifi connection on your mobile phones and then trying to connect to wikipedia via your mobile connection.  

Gazillions of is it down websites...

restart router, restart pc, restart mobile phone, clear browser cache 

 

can you get to other websites?

 

could be a DNS issue at yuor ISP if you're using their DNS servers

 

 

Seems to have been Router problem. Turned it off for  couple of hours, now all OK. Thanks for all help / advice/ replies.
