[caiu] Intermitência Google via PTT

Quarta Junho 25 11:09:43 BRT 2014

Eduardo e Israel,

Obrigado pela resposta, não tinha visto o histórico da lista, é que mesmo o Google limitando pings conforme informado nessa resposta deles, nunca tivemos perda de pacote para esses destinos.
Ocorreu uma breve indisponibilidade no nosso acesso agora a pouco e vimos essa perda logo em seguida.

O acesso normalizou e a perda de pacotes continua, realmente a informação procede.

Obrigado,
Thiago Bueno

Ia falar o mesmo Eduardo.

Mas segue a resposta do google.

> I understand from your problem report that you are seeing some packet loss to Google servers when you are running ping. Aside from the results shown by ping, are you or your users experiencing slower access to Google services? Are you unable to access Google services at times? Are you seeing any other type of abnormal behaviour when attempting to access Google services?

>

> Google performs ICMP rate limiting on the network devices, as well as on the servers. Therefore, ping tests are not an accurate manner of detecting network degradation. Please use TCP and UDP probes to test connectivity to Google servers, not ICMP.

>

> I have tested connectivity to your IP xxxxxx and I was unable to detect any TCP packet loss, while some ICMP packet loss was seen. This shows there is no network issue between xxxxx and one of the Google servers, in spite of seeing packet loss when running ping.
