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.
Can Job Sharing Boost your Employee Profile? Job sharing is one of the newer occurring work arrangements on the job market. It means that two or more people share one full time position. Most often it is two people that work part time on the same position. This kind of work sharing is a great invention for all parents that want to spend more time with their children or for people that are just not made for a full time job. Job sharing is a flexible job option that shares one person’s responsibilities between two people. So, can job sharing boost your employee profile? Yes, of course is the answer to that. The reasons why job sharing boosts your employee profile are widely spread. Job sharing can bring benefits not only to employees but also to employers and companies. Start by looking at the aspect of sharing your work. If you are sharing a full time position load with another person, pressure is less on you. You still have the same deadline, but the pressure is shared and you can work more efficiently on your work assignments. Less stress makes for a happier more relaxed employee that can tackle the work given to him or her easily. This makes the employee a more balanced person. The possibility to stay at home while still having a chance to be part of a company can further your career and keep your skills up to date and this makes for a well balanced worker. Another reason why job sharing might boost your employee profile is that two people working part time actually can get more work done as one full time employee. Why is that? Well, that is very easy. While the full time employee is very tired in the mid afternoon from his already long day, the person coming in for the second half of the day has had time to relax all morning long and therefore can start with new end fresh energy and thoughts on the shared work. Should the position not be shared in half days, but in each taking a few full days, then the people sharing the position are still more relaxed and motivated. They are able to be with their family, able to rest and regenerate or have fun with some of their favorite hobbies. Psychologists and researchers have long praised the effect that a fun family filled time and enough time to be you and relax can boost your employees’ work input as well as their efficiency. In countries where employees have fewer hours per week and more vacation days a year, the work output per person is in general higher and employees are happy and motivated and stay with their company for long periods of time, if not all the way up to retirement. Additionally, if you have a good amount of time off from work, you are most likely a very motivated and happy employee and your boss and fellow employees will see you as a positive person to be around at the work place. Being a leader and motivator is all that a boss can hope for and therefore, sharing the position can immensely boost your profile. For employers, there is also the consideration of your benefits. Some companies might not pay benefits to part time employees and two part time positions will save you money. In this case, your profile is simply boosted by the fact that your employer saves money. Although in some companies, there are benefits for part-time employees and those can be based on different facts, such as hours worked, full-time benefits and more. Before considering sharing your job and entering the world of part-time employment, make sure that this is exactly what you are looking for in a job. Once you are sharing your position, there might not be a way back to full time, at least not within your own company.
