AS3352 blackholing geuzenveld.ripe.net


By accident (checking performance of the not-so-good UPC link),
I found out telefonica are pulling packets for tt01 towards them.

This explains the weird traceroutes from tt15 -> tt01 we've 
been seeing.

Will contact our contacts for tt15 tomorrow.

Antony, can you check what RIS sees of this?
