Changing Hosting Server
Posted 08 August 2005 - 12:15 AM
Our current hosting server has a few technical problems and gets re-started quite often keeping the site down for long periods of time. We are contemplating changing the hosting provider to a more stable server.
Firstly, will this affect my SEO efforts in any way? and what is the safest way for transition to the new hosting provider.
Second, our current hosting provider feels that the server has to be formatted which will set things right. The website will have to be down for a day(24 hours) for that. How do I go about it. This process could happen next week. Your quick response is highly appreciated.
Thanks & Regards

To the spiders that looks like the site may no longer exist. Which can lead to delisting of pages and/or PIPs starting to show up.
Two ways to approach it.
The way most people do it is upload everything to a new server and simply change the Name Server information for their domain at the Registrar. This change normally takes just 1-3 days to propagate through the Global DNS servers, though some search engines and spiders cache that data locally.
The generally accepted rule it to allow the site to stay up on both servers for 3-4 weeks if possible, so that nobody gets left hanging, unable to reach your site.
If you have the ability to edit the local DNS information on the old server you can also change that so that your A records all point to the IP number of the new server. What this does effectively is set up a sort of redirect at the DNS level. Meaning even if some search engine or ISP has cached the old IP number information, as soon as something hits the old server they are automagically forwarded to the new location.
I do it this way since I have that sort of control. It works very, very well because not only are all http requests transferred to the new server, but so is email, ftp, etc, etc. Everything is automatically sent to the new server location.
Again, it's best if you can leave this up and going for 3-4 weeks just to be safe. Although my experience has been that the engines and ISPs seem to recognize the IP number change, which appears to trigger an update in their local DNS cache.
The issue with this one, if you don't have that kind of control over the local DNS for your site at the old server (most don't) is that requesting such a change from your current hosting company will often fall on deaf ears. They know very well that such a change means you're leaving them for another host. Right or wrong, they're usually not very responsive when they know you're leaving.

Too funny Chris!
Though I admit the same thought occured to me. If nothing else why wouldn't they simply lease a new server (you know they're leasing already) and transfer everybody over to the new machine?
From the hosts side of things that small hit would be a lot better than losing customers over it. Especially if they're talking about formatting and starting over from scratch anyway.

The above replies have shown me the right way to go about it. I was all confused

Till we move on to a new ISP, can we host the website on a virtual machine

As our server has a problem and it may take a few days to move to the new ISP. Will it affect my SEO efforts if we host the website on another server which is a virtual machine with the current ISP. In effect the IP address of the site will change.

It's a much better alternative than have your site going offline for days at a time.

I got an update from my network department
They say that we have our own Domain name server registered with Network Solutions and the hosting provider is HostX.com. Now we are planning to buy a new server with HostY.com.
I have to update the server IP address at Network solutions and assign a static IP to my website URL. Am I right?
How do the spiders crawl websites? they resolve the website and check the physical location to get the latest data?? Am I right? if yes what info about my website is stored in their database?

Another possibility, since you mentioned leasing/buying your own server, would be to set up the server so that you run your own Nameservers. So the domain registration might read like:
Nameservers: ns1.yourdomain.com and ns2.yourdomain.com
If this is the case, you'll need to have additional IP numbers bound to your server, which will be tied to your local nameserver addresses (the ns1 and ns2 in the example above.) You'll also need to add those to your domain at the Registrar. They all calll it something a little bit different, but usually it's something like Child Nameservers.
Using HostY's nameservers would probably be easiest, as long as their helpful. Using your own name servers will give you a bit more control, in case you should ever need it.

I'm better informed about name servers after your reply
Firstly, we have our own nameservers as ns1.mydomain.net and ns2.mydomain.net and we are not changing them. We are only changing the hosting server to HostY where we are getting additional IP numbers tied to it. We will be assigning the IP address to our website.
So as a result, we have to update the server IP address and assign an IP address to the website to effect the change. How long will I have to maintain data on the current hosting server after the change?
Am I right?

Technically, you won't have to "change" the IP number of the domain itself since that will happen automatically.
The process will go like this...
- Get your site all set up on the new server, including the local DNS there. Make sure you have your NS entries in an A record that tie them to the IP numbers you'll be assigning to them.
- Then go to your Registrar and change those Child Servers slightly to make sure the ns1 and ns2 are pointing at the new server's ip addresses you have tied to those.
- That'll take some time to propagate through the Global DNS servers. It usually happens in 24-72 hours, but remember that some ISP's cache that data.
- If you have the ability to change the local DNS at the old server --it sounds like you may since you're already running your own DNS-- you can tweak it to force an immediate transfer. Just change the IP numbers listed in the various A records there so that they point to the corresponding IP numbers on the new server. Then even if the ISP's still send traffic to the old server, it will immediately forward everything to the new server.
Also note that if you have an SSL cert on the site you may need to update that. Most of those attempt to bind to a specific IP number.

I'm all set to make the next move
