Does it matter who hold my DNS SOA? - Latency

I am a UK based company with primarily UK based customers. The webserver is located in the UK, but I am looking for a good DNS host. All the good ones seem to be in the USA (offering auto failover etc).

A) If a USA based company hold my DNS records what will this do to latency for people performin lookups for websites, mail etc.

B) Also what impact does that have if i change an entry at the USA host? Will it be instant or will there be other root servers that will ahve to update.

Thanks

A) It's OK to keep your zones outside UK. US is a good choice. Users will not see any difference.
B) It will not be instant; exact time depends on zone parameters (SOA record). You will not need to update anything except you primary zone file.

Corwin77, can you point me to somewhere that justifies what you say. If so points are yours.

Are your services UK-oriented? If not, you've got the answer: US data transfer channels are generally "thicker" and better organized than any others (you noticed good service providers were located in the US, didn't you?); that means worldwide users will get faster responses. UK users will not feel any difference because of high speed channels from US to UK. Also, nature of DNS technology smooths latences. Working for some UK company gave me a chance to test these statements out.
Records and whole zone updates on different name servers occur according to the schedule, based on parameters like ttl, refresh etc. SOA record format:

The services are UK based, but I want a good DNS hosting provider. The services are all web site services. The web servers are located at redbus in teh UK.

Well, why don't you run your own DNS servers, if you have colocation in Redbus?

Yes we do but then we have a single point of failure which is the project I am looking to do now. There will also be no features such as auto failover on node down etc.
