Intermittent DNS errors. IP team not able to diagnose
-
Intermittent DNS errors showing up in GSC for our fashion portal www.AJIO.com. Our IP team doesn't find any issues at our end. Everytime i write to them, they come back saying 'DNS is resolving fine in all servers'.
How do we resolve this? Pl help

There are a few issues with the DNS that I can see. First off, the email address in the SOA record is wrongly formatted, so won't receive mail. While that isn't the source of your issue, your IT people should change it so that they can receive messages about the DNS. Change this:
to this:
jliodns\admins.ril.com.
(Copy all of that exactly, including the dot at the end of the line.)
Secondly, there are different SOA serial numbers available. There are four nameservers for ajio.com, and they are ns1.ajio.com, ns2.ajio.com, ns3.ajio.com, and ns4.ajio.com. When I query ns1, ns2, or ns4, I get back a line like this:
ajio.com. 3600 IN SOA ns1.ajio.com. jiodns.admins@ril.com. 2016052708 10800 900 1209600 86400
But from ns3 I get this line:
ajio.com. 3600 IN SOA ns1.ajio.com. jiodns.admins@ril.com. 2016041301 10800 900 1209600 86400
The difference is the serial number (the bit after ril.com.): it's 2016052708 in the first case, and 2016041301 in the second. These numbers should always be the same. It looks from this line as though the ns3 nameserver should be fetching the newer serial number every 10800 seconds, yet it clearly isn't because it has a serial number from April 2016, while the other three nameservers have a serial number from May 2016. That's still not enough to explain your issue, but basically, your IT team need to investigate the performance of their nameservers, because this may be the symptom of a wider issue.
Good places for them to start are here and here. The first of those two links is the Pingdom test that Nicolas linked to, but with the important difference that it's checking ajio.com, rather than www.ajio.com.

Take the first tool available http://dnscheck.pingdom.com/?domain=www.AJIO.com and it seems your domain have errors.

Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
We are building URLs dynamically with apache rewrite.
Intermediate & Advanced SEO | | lcourse
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0 -

Www vs. non-www differences in crawl errors in Webmaster tools...
Hey All, I have been working on an eCommerce site for a while that to no avail, continues to make me want to hang myself. To make things worth the developers just do not understand SEO and it seems every change they make just messes up work we've already done. Job security I guess. Anywho,most recently we realized they had some major sitemap issues as almost 3000 pages were submitted by only 20 or so were indexed. Well, they updated the sitemap and although all the pages are properly indexing, I now have 5000+ "not found" crawl errors in the non-www version of WMT and almost none in the www version of the WMT account. Anyone have insight as to why this would be?

Separate IP Address for Blog
Our developers are recommending we sign up for a cloud based LAMP (Linux, Apache, MySQL, & PHP) server to install 3<sup>rd</sup> party software (Wordpress). They said "the blog will be on a separate IP address and potentially can have some impact with SEM/SEO." Can anyone expand on what impact this might have versus having it on the same IP?
