Senhores,


Estou com problemas de conectividade com o UOL via PTT-SP em IPV6.

Estamos com perdas de pacotes e a latência média é de 150ms.

Mais alguém com o mesmo sintoma?

Segue testes:


traceroute to homeuol.ipv6uol.com.br (2804:49c:3103:401:ffff:ffff:ffff:1) from 2804:4ec:3::2, 30 hops max, 24 byte packets
