DNS Routing Problem on Wednesday, March 25, 2015.

On Wednesday, March 25, 2015, several DNS servers were having trouble resolving domain names. I first noticed this when visiting Daring Fireball. I was not able to load the site on my iPhone, which is on T-Mobile network. By 4:00 p.m. Pacific Daylight Time, I was still unable to access Daring Fireball on my iPhone. I took the screenshot and tweeted:

If I had to guess, it might be DNS issue with T-Mobile.

Two hours later I noticed that I still couldn’t access Daring Fireball. This time I was using the office network; connected through AT&T DSL. We could only get AT&T in this particular area. Then I tweeted to John Gruber:

It seems  is still down. 

Within 3 minutes, Gruber replied:

 No, my site is up. There are internet-wide routing problems, alas: 

Daring Fireball is still down

When I arrived at a colleague’s residence, I was able to to load Daring Fireball site through Verizon FiOS.

Later on, Ben Drago replied:

I tested a few DNS servers and some of them were having the same issues with Google DNS.

At the time of this post, the issue persists on some DNS servers.

Google Public DNS

Google has just launched a public DNS similar to OpenDNS as alternative to the ISP DNS.

Google DNS: 8.8.8.8 and 8.8.4.4

Why does DNS matter?
The DNS protocol is an important part of the web’s infrastructure, serving as the Internet’s phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.

OpenDNS: 208.67.222.222 and 208.67.220.220
