The big CDN networks do various routing tricks to try to ensure the user communicates with their closest proxy. This is normally not visible to you, so as long as you let the CDN manage the advertised DNS addresses, and let the CDN do its job, it should be doing the best it can.

There should be no need to shift existing websites onto IPv6 for a long time. IPv4 will keep running for years yet. There will be a process where new services begin to use IPv6 instead of IPv4. The two systems will co-exist side by side. To the end user, assuming they have their software up to date, they should notice no difference. If you want to test ...

IPv6 is mostly about the "plumbing" between your server and the user. The various parts of that plumbing may or may not be IPv6 compatible. Even if you make sure the network from your server to your ISP is your ISP may not support it. On the other hand, it's worth making sure your webserver software (Apache or IIS say) supports it (Apache v2.0 and upwards ...

From the GoDaddy Support Docs: NOTE: A 60-day transfer restriction period applies when you register or transfer a domain name, update the registrant contact's organization, or update the registrant contact's first or last name and an organization is not listed.

Most domain registrars require you to wait a specified period of time between transfers (usually 60-90 days) for various reasons, including fraud. I don't know about GoDaddy in terms of whether they will allow you to trasnfer the DNS, but Namecheap will get your domain registered for you and allow you to transfer the DNS right away (you still have to wait ...

Any latency you see may be due to your network or any part of the Internet between Google and yourself. As well, for shared resources such as social buttons, you will see significant lag times. This is due to the demand for those resources and the capacity to deliver the resources. Google is rather robust and can deliver ads fairly quickly, but because of ...

The short answer is, if they are just giving you a list of IP numbers, there is no way to verify that they are all owned by the company. However for large corporations, you can do a whois lookup on an IP range and determine the owner: http://whois.arin.net/ui For example, if I enter 8.8.8.8, it returns that 8.8.8.0 - 8.8.8.255 are assigned to Google, with ...

You could physically send someone to the company and check with a simple "ifconfig" what the IP is...this is a silly solution and it's pretty bad if you're based in US and the company is in AUS. You could think about something else but the point is you should avoid IP Based Authentication at all. Suppose someone knows your company and one of your customers, ...

Due to the forwarding of the email it is as simple as setting up a new forward on the new 'email hosting'. If you plan to use the home server without a forwarder then you need to use the full mx records of the home server and not the hosting package. To avoid downtime change the TTL on the domain to 1 hour and wait 24 hours of that to take effect globally. ...

If you need the ping time to a server from many different locations, one site is http://www.just-ping.com - this gives the ping time from around 50 places. There are other similar sites. Another way is to get a virtual server in country (city) one, and ssh into it, and then ping a server on country two from it. This also works in reverse. For example, if ...

The use of tools to download your files does not mean they are doing anything illegal. Infact if your files are made available on your website, I don't see downloading them in any particular way could be construed as illegal. Perhaps if the resources you make available on the website are useful downloaded en-mass, perhaps you should make a single download ...

We've addressed this from the other side on Super User as a Community FAQ: How do I diagnose not being able to reach a specific website as an end user?
