What on earth does `sliver` in `cdn-cgi/trace` means?
For example, if one does a
curl https://cloudflare.com/cdn-cgi/trace, most fields are pretty self-explanatory. However, I could not find any references to the sliver field means apart from some Cloudflare Forums posts that doesn't exactly explain it either. Just curious how it can sometimes be none and after you refresh it can become something like 010-hkg08
