Google Bug? Increase In Webmaster Tools DNS Errors?

Nov 19, 2013 • 8:50 am | comments (17) by twitter Google+ | Filed Under Google Search Engine Optimization

Google Webmaster ToolsSince November 14th, I've been seeing a large uptick in complaints about Google Webmaster Tools reporting DNS issues with sites, leading to Google not being able to index sites fully.

There is a thread at WebmasterWorld and dozens at Google Webmaster Help.

In April, Google had a bug where they sent out false DNS errors to many webmasters and told everyone to ignore them. I am not sure if this is an issue with Google or something else.

The strange part is that it coincides with reports of ranking changes that I don't see myself.

I am going to try to get word from Google about the DNS issue and see if it was a bug and/or if it may be in any way related to the changes some tools noticed in regards to ranking fluctuations on November 14th.

Forum discussion at WebmasterWorld and dozens at Google Webmaster Help.

Update: Google told me, "we're not seeing anything unusual on our end." :-)

Very timely thanks, we were just investigating this very thing for a client today. Look forward to your update.

I Think it was a very temporary issue rather then a bug, I too got DNS issue message in webmasters, Yet it got solved automatically immediately the next day. So no special efforts.

There is nothing to investigate. Neither short DNS error nor bug in reports can't affect rankings.

I got this error for three of our sites. I haven't heard of any issues on our end though. So I am guessing it was a bug.

Saw DNS issues and a drop in impressions on the 14th.

Had DNS issues and a rankings drop on the 14th. No DNS issues before or after the 14th. I wouldn't normally associate the DNS issues with a rankings drop as we've had DNS issues before and rankings didn't change, however since other people are reporting the same I'm beginning to think the too are related.

We also had DNS issues on the 14th, and the traffic drop followed today... Seems rather correlated, isn't it?

Along with the DNS issues spike, has anyone seen a huge spike in Not followed URLs on the same date? WMT lists them as URL errors, but they return a 200, get fetched fine, etc.

Hi Sam, We also have been noticing increase in Not Followed URLs but it is not on the same date but it started from the 1st week of November. All of them show as Response 302. Please share any findings that you have.

i also got a message from Google webmaster about DNS Errors and Google not being able to index sites fully.


11/20/2013 03:11 pm

I also got this error for my personal site and a few client sites. It was definitely an issue on Google's end and not with the sites. The sites were hosted on different servers too so it wasn't localised.

Was the DNS error general or localized? I did not see any such error in my webmaster tools

Same happened to me and it wasnt my server - traffic has been going downhill since

I saw this across all clients and have a feeling this has to do with the way in which Google/Chrome is resolving DNS as a reaction to NSA issues.
