UK here (well, Wales). I use marketwatch to look at prices using https://www.marketwatch.com/investing/stock/xxx
where xxx is the ticker.
It was working fine until about 10 mins ago, but now I get either 504 Gateway Time-out (nginx) or I get 500 page error (from Marketwatch).
Anyone else having problems?
Edit to add: the news bits of the site are still working for me.
