Web Hosting - Domain Name Changes and How They Affect You
New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it.
When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties.
One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another.
Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here.
DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low.
In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was.
A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed.
The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world.
Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching.
In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data.
A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed.
Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random.
But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies.
That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely.
In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address.
So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.
Tackling those Second and Third Interviews to Land that Job If you make it to a second or third interview, you are a serious candidate for the job. The key now is to narrow down the candidates. This moment is when you will determine if you get called with a job offer or receive a notice of rejection in the mail. Arm yourself with the proper tools and make an even bigger splash on the second and third interviews than you did at the first one. The first thing to remember when you are going into a second or third interview is what you said in the first interview. The interviewer will have notes from the first interview so you need to be ready to follow up on things you said initially. This is why it is important to be honest and realistic in the first interview. If you work hard to impress the interviewer and end up lying, you may not be able to recall they lies you told in the first interview. Eliminate this from being the case by telling the truth the first time around. Be armed with questions about the position and the company in generally. Search through information online about the company and get a feel for day-to-day operations. Type in the name of the company in Wikipedia and see what comes up. Many corporations are listed in this massive Internet encyclopedia and information about the company can be found there. Find out as much as you can about the company you are interviewing with. If you are interviewing with the same person the second or third time around, ask about their experience with the company. Questions like, “What is a typical day for you on the job?” or “How long have you been employed with the company?” can help to build a relationship with the interviewer. It also signals that you are comfortable with the interviewer. Not to mention, who does not like to talk about themselves? This is a great way to keep the interview moving on a positive note. Have plenty of questions about the position. Show that you have researched the job and are very confident that you are going to get it. The more inquiries you have about the position the more serious and interested you will seem. By the second or third interview, you will probably meet a number of different people. Shake hands firmly and look them in the eye when talking to them. If you are given a tour of the facilities, ask questions. Do not just let your tour guide point out areas without you taking an interest in them. Although it may seem like second and third interviews should be easier, do not let your guard down. Stay on your toes and be even more prepared than you were for the first interview. As the interview process moves on you will probably be meeting with the person that will be your direct boss or the director. Interviews with these figures may be much more difficult than the first interview which was probably with a human resource person. Be aware of this fact and have answers for those tough questions like, “What makes you the right candidate for this job?” Also be prepared for hypothetic situations that may take some spur of the moment problem solving. No matter what number interview you are on, there are some standard rules to follow. Take copies of your resume to your second and third interviews. Even though the interviewer may have a copy of your resume, you want to be armed with extras just in case there are other people in the department that would like copies. If you meet with different managers they may all ask for copies of your resume. Yes, they have copies, but they want to see if you are prepared. To Enter or Not to Enter Writing Contests (writing contests) If you are a freelance writer, it is because you love to write. Why not put those abilities to use and enter a writing contest? You have nothing to loose and a lot to gain. You can find writing contests by simply searching the Internet. Writing groups and message boards may also have listing for these contests.

This feedback and criticism is even more important than the first. Do not your eggs all in one basket. Enter a couple contests to get multiple feedback sources. Not every editor or agent is going to agree. By entering multiple contests and find common points about your writing that need perfecting you will be able to concentrate on a general consensus about your abilities. There are some downsides to entering writing contests, too. Chances are that a simple contest is not going to launch your career into star status. Do your research just as if you were going to write an article about contests. For many contests you give up your rights to your entry whether it wins or not. You need to decide whether or not you are willing to give up all rights to your story. If you win it is not a big deal, but if you loose your giving your work away. Are you willing to do this? Research the contest. You can search the Internet for reports or opinions on contests run by the company. You can find valuable information on if the contest is legitimate, if entering has had any effect of previous entrant’s careers, and if it is really worth it in the long run. The bigger and well-established companies will give credibility to your work if you win. But the bigger and more well know the companies are will also bring in tougher competition with well know authors. Some companies offer contests as a disguise. Yes they will give away prizes and declare winners but their main goal with the contest is advertising. It can be in the form of offering you to buy obscure book featuring your contest submission. Sometimes it is an editing company that offers a discount for its services or a company that will offer you discounts on writing classes. A writing contest is just a possible stepping stone. Whether it helps you or not is the unknown, but it definitely won’t hurt you. It may help you reach the next level of your career. You and only you will be able to make the decision on whether or not writing contests are a good move for your career. |
