We see that too
Predominantly seems to be massive amounts of /24s in a couple of nets
which were previously /16s. Culprit would appear to be AS705
*>i63.0.0.0/24 62.24.196.1 100 0 286 209 701 705 i
*>i63.1.0.0/24 62.24.196.1 100 0 286 209 701 705 i
*>i63.2.0.0/24 62.24.196.1 100 0 286 209 701 705 i
.....
Lots of new /20-24 in 67.0.0.0/8 also AS705
In total AS705 is announcing 4432 new routes from yesterday.
If you're interested a copy of all new routes since yesterday is at:
