Google’s Public DNS intercepted in Turkey
2014年3月29日
Posted by Steven Carstensen, Software Engineer
We have received several credible reports and confirmed with our own research that Google’s Domain Name System (DNS) service has been intercepted by most Turkish ISPs (Internet Service Providers).
A DNS server tells your computer the address of a server it’s looking for, in the same way that you might look up a phone number in a phone book. Google operates DNS servers because we believe that you should be able to quickly and securely make your way to whatever host you’re looking for, be it
YouTube
, Twitter, or any other.
But imagine if someone had changed out your phone book with another one, which looks pretty much the same as before, except that the listings for a few people showed the wrong phone number. That’s essentially what’s happened: Turkish ISPs have set up servers that masquerade as Google’s DNS service.
If you could tell a user three things to do to stay safe online, what would they be?

At Google, we’re constantly trying to improve security for our users. Besides the many technical security features we build, our efforts include educating users with advice about what they can do to stay safe online. Our
Safety Center
is a great example of this. But we’re always trying to do better and have been looking for ways to improve how we provide security advice to users.
That’s why we’ve started a research project to try to pare down existing security advice to a small set of things we can realistically expect our users to do to stay safe online. As part of this project, we are currently running a survey of security experts to see what advice they think is most important.
If you work in security, we’d really appreciate your input. Please take our survey here:

With your input we can draw on our collective expertise to get closer to an optimal set of advice that users can realistically follow, and thus, be safer online. Thanks!
Staying at the forefront of email security and reliability: HTTPS-only and 99.978 percent availability

Your email is important to you, and making sure it stays safe and always available is important to us. As you go about your day reading, writing, and checking messages, there are tons of security measures running behind the scenes to keep your email safe, secure, and there whenever you need it.
Starting today, Gmail will always use an encrypted HTTPS connection when you check or send email. Gmail
has supported HTTPS
since the day it launched, and in 2010 we made
HTTPS the default
. Today's change means that no one can listen in on your messages as they go back and forth between you and Gmail’s servers—no matter if you're using public WiFi or logging in from your computer, phone or tablet.
In addition, every single email message you send or receive—100 percent of them—is encrypted while moving internally. This ensures that your messages are safe not only when they move between you and Gmail's servers, but also as they move between Google's data centers—something we made a top priority after last summer’s revelations.
Of course, being able to access your email is just as important as keeping it safe and secure. In 2013, Gmail was available 99.978 percent of the time, which averages to less than two hours of disruption for a user for the entire year. Our engineering experts look after Google's services 24x7 and if a problem ever arises, they're on the case immediately. We keep you informed by posting updates on the
Apps Status Dashboard
until the issue is fixed, and we always conduct a full analysis on the problem to prevent it from happening again.
Our commitment to the security and reliability of your email is absolute, and we’re constantly working on ways to improve. You can learn about additional ways to keep yourself safe online, like
creating strong passwords
and
enabling 2-step verification
