<i>At that very moment the Internet in China went down - with a few exceptions (VPN users and those who had the DNS cached within their client).</i><p>Hmm... perhaps I should stop using DNS to resolve the IP addresses of my VPN servers. I thought I would be safe because I use Google's DNS servers but, according to greatfire.org[0]:<p><i>However, during that time, we see that a lookup to 8.8.8.8, a public DNS operated by Google, returned bogus results if the lookup was done from China. In fact, the Google public DNS was not poisoned; the bogus response 65.49.2.178 could only have been returned by GFW. If the Chinese root DNS server was hacked, a DNS lookup in China via 8.8.8.8 should have returned a correct response.</i><p>I live in China but am away at present, so wasn't affected. Phew.<p>[0] <a href="https://zh.greatfire.org/blog/2014/jan/internet-outage-china-jan-21" rel="nofollow">https://zh.greatfire.org/blog/2014/jan/internet-outage-china...</a>
