L(o*62).ong
Make your URL
looooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooonger
A domain name can be registered with up to 63 characters, so I registered loooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo.ong.
Then I created an interesting URL lengthening tool, which is this page you're
seeing now.
The maximum length for a domain name is 253 characters, hence Longer than Long was born.
I encountered quite a few issues during the process, which I've documented
in this Github Issue. Feel free to join the discussion.
