I cannot access my assets canister since a couple of minutes. Likewise, cannot access the Motoko Playground nor the internet identity.
I either get 500 errors Internal Server Error or invalid SSL certificate.
https://status.internetcomputer.org/ reports no errors 
.
Anyone notice the issue too?
Yes, even https://nns.ic0.app/ cannot be opened
Everything seems to be down 
Good to hear I am not alone.
The dashboard also displays that everything is alright 
Ok folks, I get it, I’ll stop my DDOS attack. 
I’ve used this in the past for dynamic ssl allocation. GitHub - auto-ssl/lua-resty-auto-ssl: On the fly (and free) SSL registration and renewal inside OpenResty/nginx with Let's Encrypt.
It seems that everything on the domain ic0.app is not responding
Looks like the SSL certificates expired about 30 minutes ago?
I’m excited for the post-mortem on why this happened
Ahoy ICP folks!
I can confirm that the issue has been fixed: InternetComputer Status - Boundary Nodes Connectivity Issues
and that we are working on an incident report (still investigating and confirming root causes).
Thx for the feedback @diegop 
There seem to be quite some delay between the status and the effective issues, I mean, while the issue was effectively happening, the status page was still displaying zero problems and was displaying that everything was alright.
Is this also known and tracked?
Definitely. It was certainly unfortunate and not the experience we all want for the IC.
Thanks, looking forward to the details. In addition to understanding the technical issues, please unpack the implications from a single-point-of-failure “off-switch” perspective.
