Came across this admittedly weird issue. Randomly over the past few months, I try to go to Facebook or Twitter and end up being redirected to another website, usually MySpace. See screenshot for an example of what I saw a few moments ago.
They also posted a fix — flush the DNS cache on your local system via the command:
So what could be causing this issue? I thought it might be some sort of DNS hijacking but everything I could check seemed OK. It happens to multiple computers on my network. Finally a comment on that threat points over to the Linksys forum about DNS issues with many others having the same problem. It appears that it might be some sort of Linksys firmware issue.
Other specifics of my network – I have one router running stock Linksys firmware (WRT310N) and an old model WRT54G running Tomato firmware. I have the WRT310N getting DNS from the WRT54G, and the WRT54G is using OpenDNS servers for DNS resolution.
Next time this happens I’m going to use wireshark to try to get some insight into the problem.
Is anyone else seeing this weird issue?
