[GTER] Uol perdendo pacote ipv6

Bom dia Alexandre,


Ainda continuo com problema de latência ao UOL. A percepção de navegam é estranha pois os textos carregam imediatamente porém as imagens custam a carregar.

Segue o trace de uma de minhas máquinas:

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
 1  2804:4ec:3::1 (2804:4ec:3::1)  0.472 ms  0.287 ms  0.24 ms
 2  as7162.saopaulo.sp.ix.br (2001:12f8::12)  10.571 ms  10.312 ms  10.286 ms
 3  2804:49c:aaaa:a11:ab1e:6:0:1 (2804:49c:aaaa:a11:ab1e:6:0:1)  153.487 ms  153.494 ms  153.179 ms
 4  * * *
 5  * * *
 6  * * *

O ping também fica bem alto e com perdas de pacote:


PING www.uol.com.br(2804:49c:3103:401:ffff:ffff:ffff:1) 56 data bytes
64 bytes from 2804:49c:3103:401:ffff:ffff:ffff:1: icmp_seq=1 ttl=51 time=153 ms

64 bytes from 2804:49c:3103:401:ffff:ffff:ffff:1: icmp_seq=10 ttl=51 time=152 ms
^C
--- www.uol.com.br ping statistics ---
10 packets transmitted, 8 received, 20% packet loss, time 9009ms
rtt min/avg/max/mdev = 152.598/152.853/153.762/0.406 ms



Detalhe, se removo meus anúncios do PTT e fico somente via Trânsito (Durand), tudo volta ao normal. Ping em 10ms e navegação OK.


Aguardo um retorno.
