Getting redirected to wy-in-f147.1e100.net

I am a MAC OS user, more precisely I'm running snow leopard.

Today when I tried to access google I was redirected each time I've entered "google.com" (or any other google service, e.g. gmail), whether using Chrome or Safari. In gmail开发者_Go百科 case I was prompted to accept an certificate belonging to akamai.net.

After this I opened a terminal and did a traceroute to google.

The traceroute showed me that google.com was wy-in-f147.1e100.net. Knowing this, I cleaned my DNS cache, solving the redirecting problem.

I would like to know if this problem is known and what may have caused it.

I just did a quick

whois 1e100.net

and it gave me

Domain Name: 1e100.net

    Registrar Name: Markmonitor.com
    Registrar Whois: whois.markmonitor.com
    Registrar Homepage: http://www.markmonitor.com

So it checks out.
