Why doesn't the site https://meta.discourse.org/tags exist?

Maybe I’m picking on the details, but it’s weird because
there is only page:
https://meta.discourse.org/tags working ( meta.discourse.org/tag is not working)

but google indexes pages like https://meta.discourse.org/tag/tag-number-555

I think it’s not readable to the robots and and it is bad for indexation

Please rephrase your question. I don’t understand what you are asking in the topic subject. :sunglasses:
