Does IP Changes Affect SEO Metrics?

[Jinx14678]

Okay,

So yesterday I asked a question about setting up custom error pages in IIS 6.0 to properly do a 24 hour 503 Service Temporarily Unavailable. With no answer, (not to the despair of the community as the question has NO simple or easy answer

So after a night of dreaming about solutions

I realized that we have the ability to just clone the site.... So basically it would just become a redundant server or mirror site for 24 hours.

With all that being said the question is.....

What SEO pitfalls might I encounter from this if any

I suspect none as load balancing and redundancy is a fact of life in the WEB world, especially since it will be a MAX of 24 hours downtime for maint.

I have lost my window

The admin team has already began tasking and beginng save.... It is a major Virtualization migration, and my requests had to be in by yesterday. Ohh well, it will be only 23 hours and i convinced them to just route to a shutdown pool generating a 503 since they will not cloine this late....

Thanks for the help though i will keep this in mind for next time ( but i get my brand spanking new virtual environment next month soooo i will be able to have more wiggle room)

I just read your other question and I think the answer to all your problems are relatively simple: Since the server is going down for maintenance (usually a geeky way of saying we need to fix something, but without admitting that anything is broke) chance are that it won't be going down again any time soon. So the solution is straight forward.

1: Clone your site to another server.
2: Change the TTL to something like 3600 (an hour)
3: Setup your zone file on the new server to accept the domains and subdomains.
4: Change the IP of all the A-records relating to your site, to point to the new server

When the server guys are done fooling around.

1: Change the IP back to the old server
2: Change the TTL to something like 43200 (12 hours)

Problem solved and Google won't hate you

Hmmm so it sounds like it may not affect as the change is being made internally at the firewall through tables, and should not affect TTL since the domain is still going to the same nameserver.

Last nights question http://www.seomoz.org/q/how-add-503-status-to-iis-6-0

I found a few crack hacks, but did not like any of them especially since the IIS has multiple pools with applications on them.

Thanks for the help I love the discussion

Since you sound like, you know your nerd speach. I'll go tecno

A domains TTL has an impact on your SEO efforts. Low TTL's makes it possible to cheat Google's clients, hence Google doesn't like this. (since you can change where the client is sent every few seconds.) How much it effects your efforts, I must admit I have never tested.

Just in case you do not know what a TTL is (I suspect that you do though): TTL stands for Time To Live and tells the Name servers how often they should revisit the domain host and retrieve a zone file for the domain. In  other words TTL determins how often the name server checks to see if a DNS record has changed.

What was your question from last night? could you link me? I won't promise anything, but one never knows I might know the answer for that one
