Just to clear up some misinfo circulating, a BGP hijack was not the cause of
Cloudflare DNS going down today.

At 21:51 UTC, Cloudflare (AS13335) withdrew both 1.1.1.0/24 and 1.0.0.0/24 for an unknown reason.

I suspect AS4755 was always announcing 1.1.1.0/24, when CF went away, it leaked a bit (i.e. "%2").
