We (as3215) are seeing almost the same path with 40633 18978 3257
3215, for some quite a lot of prefixes.

Some alerts from bgpmon:
193.251.32.0/20 271 6939 40633 18978 3257 3215
193.251.32.0/20 271 6939 40633 18978 3257 3215

We are not directly connected to 3257. Looks like 18978 deaggregated
to /20 and reannounced to 40633 (LAIX).


Rgds,
pierre
