Google DNS

how frequent do they update

[phish]

Believe it or not I had a server crash during this mess we call an update. I had to switch boxes resulting in a new IP. How long does G usually take to update their DNS? I cant tell if Dominic dumped me or I just havent been found yet.

Update Your Domain's DNS "Start Of Authority Record" to a serial number greater than the old one. The best way to do this is today's date plus 15, i.e.: 2003052815. Google's root DNS server will see the new serial number and should find your new I.P.

Normally, search engines ignore search engine TTLs.

Browsers and proxy caches make relatively few DNS lookups as users tend to visit the same sites again and again. Search engines have to crawl many domains, often without fetching a particular page again for a month or so. This was a significant issue in the early Brin/Page papers.

phish, given that the link: results and Toolbar aren't in line with the results, I don't think that there's much point trying to find your status in Dominic. Time will tell.

Google increased their frequency of DNS refresh last year, so nowadays it's not as much of a problem as it once was.

I changed dns a week ago today and google is the only one still hitting the old site, so I think they update slower than most.

My pre-Dominic experience is that they are typically 30 days out of date. Now there's no way to tell. I still don't understand why it's such a big deal you use the same dns as the rest of the planet, in fact I would think it would be a major priority.

Google caches their DNS lookups to save time - if you have multiple bots crawling the same site over a number of days you don't want to have to look up the IP address every time.

i changed dns 3 weeks ago

googlebot was hitting the old site till May 25 after this date it started hitting the new site ,no hits at the old server

As I posted elsewhere before I found this thread, I recently spoke to a well known SEO who has a site waiting 4 months for the new DNS to be picked up & no joy.

It'd be cool if we could get our hands on an "Update History" for DNS as opposed to just 'Dance' history.

Ccowboy - Has what you suggested worked more than once for you?

Need to get a big problem I have solved asap :)

If possible you should set up a proxy on the old server to proxy the web site from the new IP address. Thus any requests for www.mysite.com which come through to the old address get to se your current site.

That sounds good Netizen
Any clues or URL showing how one might do that? I'm not the most techie!
