Google DNS Update

Looks like they've finally updated.

Hi all,

My new IP addresses got picked up for the first time in 2mts today. I guess that means G have updated thier DNS records right?

Would make sense. Were these sites not in Google during these 2 months? I'd think Google could update DNS a lot more frequently than that.

[Nick_W]

No they were in Google, she was just spidering the old IP's is all. Now the new IP's are being hit as of late last night...

Good about time 2. I hope it got mine 2.

Yes, I think Google updated his DNS-Database to prepare the Deepcrawl. This is the best time for google to update it. So the Deepcrawler can start his work with actual DNS-Entries.

I don't know much about Google and DNS. Are you saying that if your IP numbers change that can have a negative impact on your position?

I hope not because I am currently switching my T1 from Global Crossings to USLEC.

That would be bad!

well fwiw I switched to a new server jan 1st 2003 and since this update, serps have nosedived.

How long was that Nick? It doesn't feel like long since you switched.

Did you find any hits from Google on the old IP after the first hit on the new IP? Also it would be interesting to know if the Freshbot DNS updates at the same time as the deepbot DNS.

If anyone else has access to both sets of logs after a DNS change, please post the results as it's a frequently encountered problem and if we could get an idea of the timescales a lot of people would be interested.

Jim, if possible keep the site up on both IPs for a while. It will normally take some time for search engines' to catch up with the DNS change so you may be unreachable for a while otherwise.

28th of December
No hits at the old IP once it had the new (Freshbot)

I sure hope it updates at the same time as deepcrawl bot, I just deleted the old sites!

This is old news, but when I changed in Oct googlebot found the new IP within three days. Probably because I moved just before the expected deep crawl. However, the freshbot continued to go back to the old IP until the next update when it started crawling the new IP.

I kept the old site up with a 301 but even after the freshbot found the new IP it went back to the old IP a few more times for a couple of pages. No rhyme or reason to the pages it went back for as they had never changed names or been duplicated.

I can confirm freshbot appearance after a server switch a month ago. Yesterday on one domain, today on another. After the switch the deepcrawl bot did came once but the freshbot keeps coming on the old server, until yesterday/today.

[Nick_W]

Okay, consider it confirmed that Google has updated the deepcrawl DNS at the same time ;)

I moved my site to a new server and a new IP on January 23rd. Googlebot came for a first visit on January 26th, crawling 6 pages (out of 204). After that I had three more visits, each time increasing the number of crawled pages(reaching 199 pages during the last visit, yesterday). I probably tried a dangerous strategy, but I updated the robots.txt of the old site, as soon as the new one was up, preventing the access of any kind of robot (User-agent: * Disallow: /), while keeping the old site up just in case something went wrong. The main idea was to prevent googlebot from finding two identical sites at two different IP's, which could have been duplicated content: I figured that I would have rather played a fair game, and it seems that Google appreciated that... I wonder, by the way, if and how all this is going to have an effect (either positive or negative) on the results of February update...

A website of me which I switched to another ip-address is also spidered on the new ip-address! Only Askjeeves / Teoma is now still spidering the old version...
