Telecom Malaysia (AS4788) was leaking a full routing table to a Tier 1 network, Global Crossing (AS3549), who in turn was advertising the prefixes to its peers like Level3 (AS3356). Large portions of the Internet would have been affected.
This is a double fail, both for Telecom Malaysia for leaking a full routing table, and for GBLX who apparently isn't filtering prefixes from their downstream customers or even restricting to a max number of prefixes.
- namecast 11y agoI just remembered, GBLX was bought by L3 a few years back - I'm guessing someone has a "tighten up route maps for GBLX ASN" ticket open in their backlog at the Level 3 NOC. The people managing peering for AS 3356 and AS 3549 should be the same group, no? ("That DB we don't share the URL of" seems to imply as much.)
