Sorry for the issue, can you please confirm if this is still the case as Cloudflare had a network issue recently which is now resolved. Also, what is your reason for saying that it is ‘ALL websites’ in the Netherlands?
If it is still not resolved, here is some information about the errors:
A 520 error occurs when the connection started on the origin web server, but that the request was not completed. The most common reason why this would occur is that either a program, cron job, or resource is taking up more resources than it should causing the server not to be able to respond to all requests properly.

I’ve analyzed the access log but cannot find anything out of the ordinary there. Looks like the request doesn’t even hit the server or the server gives an ordinary 200. I see requests coming in from Cloudflare IP’s but not sure where they are located. Like said before, from another country it works fine (see the post by @JoeyZo, Canada works), I’m running through a US VPN to make it work for me.
Same issues all day today (9:00am 10th June). Nothing has changed on our origin host and I’ve confirmed resources aren’t maxed. Seeing the SSL Handshake failures and Cloudflare error pages intermittently thrown from the Amsterdam edge at Cloudflare.
Took one of our sites down to DNS only on the control panel and that site has been without issues.
Very good question and I am afraid I don’t know the answer! I guess it may be because they are not sure if there is an issue and want to do some checks before they publish something there. There sometimes is a bit of a delay between reporting and an update appearing there while they do a first look into the issue.
