Issues with 23.1.64.0/20?

Anyone else see anything / know of any odd behavior on the prefix yesterday afternoon/today?

Here in Miami (NAP) we saw some issues through one of our upstreams and ended up disabling the BGP session, then re-enabling it with a filter to block said prefix.

We've since removed the filter and things are stable but would be nice to know what broke 'out there.'
