Not effect in any ways.if your start up websites,you will go to with seo works

Not really. Do some searches for local cities, then trace their sites back to see where they're hosted. Typically no where near that location.

There is no effect of data center on the website. But prefer the host from your own country.

Infrastructure that's beyond your control doesn't effect rankings.

Matt Cutts recently announced this on his blog. If your site goes down because of hosting problems - you won't be penalized for it.

From what I know datacenters have no direct impact on your seo but it has an indirect response on it in terms of your website's loading speed.

If your datacenter is located in the US and your visitor is coming from Asia, your website will load slower compared to if your datacenter is located in Asia.

Hope that makes sense.

A good way for this is to setup a CDN like Cloudflare. They have multiple datacenters located around the world which will load your website according to your visitors' location. I have written more about it in my guide in speeding up your website here.

I think no any problems for that hosting related make sure SEO factors use it you have submit your website any other country also.

I second SeoAce's advice. It's an indirect impact, because it will affect your sites speed. There are tools (caching, CDN) to to improve speed though.
