I’ve just surf International BGP routing table and found that OIXP’s ASN has leaked to International.
There are 135 prefix leaked.
I had quick a look who leaked this prefix going to International. ASN 7473 is STiX and so AS 23947 advertising their customer prefix to 7473. However, I think they are missing some configuration in BGP policy.
From CIDR I saw this AS is belongs to Cepatnet.
Quote from www.cidr-report.org:

Pertanyaannya agak terlalu global nih, agak susah jelasinnya mau dari mana. Tapi intinya satu, biasain pake BGP looking glass
