Same here
I am able to enter the instance when I use “incognito” in chrome. It doesn’t work without incognito. Also edge works without incognito.

This actually worked for me 
so weird.
Thanks @sanhup !!!
Wild, worked for me too. I guess i’ll go incognito for a while. Thanks for the tip
Quick workaround: Please try opening your instance in a private/incognito window or clear your browser cache, then retry. This has helped some affected users.
Next update: We’ll post updates on our status page: https://status.n8n.cloud/
cheers,

Claims to be resolved on the status page, as well as appears to be working on the normal Chrome as well. 
Would love to hear what had gone wrong, @jamiemadden_n8n !
Seems very similar to the issue, where Cloudflare DDoS’ed themselves in September.
