Sounds like you visited the Blackhole. You can visit the Bad Bots screen to delete your IP. Then you will have access again, but only once or you will need to delete your IP again.
Mhhh but when i blocked, why Pagespeed Insights blocked too? Its a Check from Google Servers, not from my IP.
I delete all IP’s and Pagespeed works again… strange.
Because it’s requested from your IP address. The Blackhole works by blocking any IP that visits the blackhole link. So unless you visit via proxy, or your ISP changes your IP dynamically, any request you make from your current location is going to have the same IP address. I hope this makes sense.. you may want to do some research on how IPs work, in order to understand what is happening. It’s more than I have time to explain here.
Thanks. Sorry… I did not know that Pagespeed use my own IP for the Request and some language problems 😉 Now i understand.
