1. Overcrowded servers
This is one of the most common problems of web hosting industry (in that it concerns a virtual hosting). Although it is not innately problem virtual hosting. This problem is usually associated with poor management of server resources, poor business planning and reactive rather than anticipatory behavior hosting company.
This is one of the first problems to which should pay attention to when choosing a host. If the buyer (and I think it is you) chooses before deciding to buy, and in doing so knows that go, and, just as importantly, knows what to guard against, all should be in order.
2. Security issues
In an ideal world, all you need to be done by web hosting companies - a server to connect to the Internet and to ensure that the server worked without problems. But the Internet can not be described as peaceful place. There is a wide variety of “internet terrorists.” Sometimes they are called hackers. No matter how you call them. It is important that they make the life of every decent hosting business harder than it should have been.
However, hackers and crackers - is extreme case. The network ordinary people are not like in real life. When hundreds of people had access to a computer (the server), it is likely that one of them will not entirely honest.
In addition, a virtual hosting environment can often find that you can easily get access to the accounts of other persons (collectively account when hosting - it is actually a directory (folder) on the hard disk server). Fortunately, the situation is not alarming, because, in most cases, what you save on the server, in any case, is for the public.
But there are a lot of things you have to keep secret. For example, if you sell software, you will not be able to afford such “leaks”. If you have a newsletter and you have saved email addresses of its subscribers to the server, you will likely not want to fall into the wrong hands. There are many examples, and that a few of the obvious examples.
In most cases, the security server, which hosted many websites, worse than that of a dedicated server. Usually, as in real life, there is a compromise between security and freedom.
3. Problems related to the Neighborhood.
What I call the “neighborhood problems” - a complex problem, but they all have one feature: they all relate to the fact that other people are doing on the server. These people (and their Web sites) are very close to your neighbours online and are also important as your neighbours in real life.
If one of those neighbors using an account in order to test a new script (and he is not the master of his case), then you (and all others on that server), there is a risk that one day one of those poorly written scripts may withdraw server failure.
One of your “neighbors” can belong to a curious type. Sometimes, it sometimes happens that the person has the necessary knowledge to access files in your account. As if someone completely searched your house. And although the cause can serve as a mere curiosity, unless it can be a serious excuse?
Also, there is another related to the Neighborhood thing, but for the most part, it concerns the Internet’s inner workings, but not people. This is connected with the work of search engines and Web hosts. In hosting environments used collectively IP addresses are allocated dynamically. Furthermore, the server where your hosted Web site can be hosted sites for adults and from time to time they may be attributable to the same IP address as you.
If the search engine will determine (erroneously) that the IP address associated with the site “for adults”, then your website can be considered relevant to the subject and eliminate adult filter “search engine, which can lead to a reduction in the number of visitors to your web site.
The easiest solution would be to ask your own IP address. Unfortunately, some hosts do not provide this service. Others are asked to pay extra each IP address, which usually is about $ 2 a month. Still, there are hosts that from the start will give you an IP address, although this does not mean that they do it for free. The price may be a little higher, as such a right is given to you “by default”.
The best hosted on those servers that do not have web sites for adults. Some hosts using the following technique: they host web sites for adults on some servers and websites general use - in the other. Also some hosts do not provide hosting services web sites for adults, while others host very similar websites. The
