The initial redirect has the header "Server: Apache" (unusual for Google) and an "Age:" header (suggesting a proxy). The RTT (1ms) and TTL (63) suggest the TCP connection was terminated near the client. Seems like a broken, malicious or compromised transparent proxy - very interesting if this is being seen on several unrelated networks?

Yes, this was seen in several unrelated networks this morning. Did some research and seems to be there was a problem in the caching devices of the major two carriers in Colombia. As of right now it's fixed.

Quoting Manuel Humberto Santander Pelaacuteez:Did some research and seems to be there was a problem in the caching devices of the major two carriers in Colombia. As of right now it's fixed. Wait... Columbian ISP carriers are hijacking browser traffic, and redirecting it to their proxies "To cache it", on a routine basis? |
