Telia Not Withdrawing v6 Routes

Probably a ghost route. Such thing happens :(

Their (nice) LG shows that it's still advertised from a router of theirs in Frankfurt (iBGP next hop ::ffff:2.255.251.224 – so by the way they use 6PE).

Your best option would probably be to re-advertise the exact same prefix, then re-withdraw it, then yell at Telia's NOC if it fails...

Some years ago we experienced something similar (it was a router of TI Sparkle still advertising a prefix of us in Asia to their clients, that they were previously receiving from our former transit GTT – we were advertising it in Europe...).
