Web Hosting - Changing Web Hosts, Pitfalls and Planning
At some point, nearly everyone finds it necessary to change web hosts. It may be just a migration to another server, or it may be changing web hosting companies entirely. Either way, the process is fraught with potential dangers. But there are ways to minimize the odds of problems and maximize your changes of a smooth migration.
Plan, plan, plan.
Make a very detailed list of everything that is on your current system. Review what is static and what changes frequently. Note any tailoring done to software and files. Be prepared to remake them if the systems aren't transferred properly or can't be restored. Keep careful track of all old and new names, IP addresses and other information needed to make the migration.
Backup and Test
Backup everything on your system yourself, whenever possible. Web hosting companies typically offer that as a service, but the staff and/or software are often less than par. Often backups appear to go well, but they're rarely tested by restoring to a spare server. When the time comes that they're needed, they sometimes don't work.
Do a dry run, if you can. Restore the system to its new location and make any needed changes. If you have the host name and or IP address buried in files, make sure it gets changed.
This is often true of databases. SQL Server on Windows, for example, picks up the host name during installation. Moving a single database, or even multiple ones, to a new server is straightforward using in-built utilities or commercial backup/restore software. But moving certain system-related information may require changing the host name stored inside the master database. Similar considerations apply to web servers and other components.
Accept Some Downtime
Be prepared for some downtime. Very few systems can be picked up, moved to another place, then brought online with zero downtime. Doing so is possible, in fact it's common. But in such scenarios high-powered professionals use state-of-the-art tools to make the transition seamless. Most staff at web hosting companies don't have the skills or the resources to pull it off.
Prepare for Name Changes
One aspect of moving to a new host can bedevil the most skilled professionals: changing domain names and or domain name/IP address combinations.
When you type a URL into your browser, or click on one, that name is used because it's easier for people to remember. www.yahoo.com is a lot easier to remember than 209.131.36.158. Yet the name and or name/IP address combination can (and does) change. Still, specialized servers called DNS (Domain Name System) servers have to keep track of them. And there are a lot of them.
There may be only two (rarely) or there may be a dozen or more DNS servers between your visitors' browsers/computers and your web host. Every system along the chain has to keep track of who is who. When a name/IP address changes, that pair has to be communicated to everyone along the chain, and that takes time.
In the meantime, it's possible for one visitor to find you at the new place, while another will be pointing to the old one. Some amount of downtime will usually occur while everything gets back in sync.
The Little Gotchas
But even apart from name and IP address changes, there are a hundred little things that can, and often do, go wrong. That's not a disaster. It's just the normal hurdles that arise when changing something as complicated as a web site and the associated systems that underlie it.
Gather Tools and Support
Having an FTP program that you're familiar with will help facilitate the change. That will allow you to quickly move files from one place to the next to do your part to get the system ready to go or make repairs.
Making the effort to get to know, and become friendly with, support staff at the new site can be a huge benefit. They may be more willing to address your problem before the dozen others they have to deal with at any given moment.
Ok. On your mark. Get ready. Go.
Making Effective Web Publishing Content (web publishing content) Web publishing content is important for a successful website. The content of a web site can often make or break that site, and it is important to make the site as attractive as possible, without over doing it. The content of a web site must be updated on a regular basis to keep web surfers coming back. Updated web content not only keep surfers coming back, but is also indexed more frequently by search engines. Fresh material is one of the key aspects of successful web publishing content and may generate fresh faces to a web site. One way to update the content of a web site is to update the existing web pages. Providing new content could include updating the conditions of a service, adding a new product or service, or creating a turnkey solution that will save the customer’s money or time. The web content should reflect the most recent information about a business. It is simple to provide changes to the web content, but many web sites provide updates without providing a notice. So, it is indicative to provide a notice of change each time web publishing content is changed. The announcements should be displayed prominently on the web site so that all surfers are able to see. It is also important to write articles for the web site. Articles can be seen as a valuable source for a web site’s success. The articles can be used to educate visitors on the web site and the business, while showcasing the owner’s expertise. Articles can be posted on the web site or used in a newsletter and submitted to other newsletters and web sites for syndication. This web publishing content can be used by other web site owners, which will provide leverage to the articles while generating publicity for the author and the author’s web site, while exposing them to new audiences. Writing an article seems simple enough, but there are many web site owners who are unable to find topics to write on. However, topics may be more evident than most web content writers may think. Topics for articles can be found in the news, in conversations with clients and colleagues, in networking events that are attended, and even in speeches. Blogging is also an excellent way to expand your list of web publishing content. Most web site owners can benefit from learning to blog, learning to start a blog, learning how to gain readers, and learning to make money from blogs. Blogging is becoming one of the most popular tools for showing new content on a web site. A web log can be used to answer web site visitors’ questions, inform users about new services and products, and to keep them up-to-date on industry news. Blogs are a great resource for sharing opinions and displaying expertise. The blog can be used to help an owner connect with their web site visitors while generating new web site content. Updating web publishing content on a regular basis is vital to the success of a web site and very important for many web site owners. Articles, newsletter, and blogging should be a part of a regular business schedule, and will work perfectly in keeping a web site owner connected to their visitors. The quality of the web content on a web site can make it more attractive to users or can make it very unattractive to users. Owners should use their expertise to provide writing that is interesting and necessary. Visitors will appreciate the extra effort and owners will get the rewards of maintaining good web content for their users. Preparing Questions to Ask in your Upcoming Job Interview When you get ready for a job interview, chances are you have spent a lot of time trying to guess the questions you will be asked and prepare your answers to them. How will you explain that gap in your work history? What will you say when they ask you why you left your last job? In the rush to make sure that you have all of your answers perfectly prepared and ready, don’t forget to prepare a few questions of your own to ask the person who is interviewing you. Asking questions is an important part of your interview. When you get asked the old “do you have any questions for us” one, it pays to actually be able to come back with a few questions instead of a, “no, I don’t think so.” Asking questions will show that you are engaged in the interview and have done some thinking about the position, plus, the questions you ask will help you elicit valuable information you need when you have to decide whether or not to actually take the job, should it be offered to you. The first thing you should want to find out is why the job is open in the first place. Is the job you are applying for a new position? That means you can expect to have a lot of transitional bumps along the way as you are integrated into the company. If the job is not new, and the person before you was fired, then you can expect things to be in a state of disarray when you take over and that you will have to spend a lot of time up front cleaning up spilled milk. If the job is open because the person who had it before you moved up in the company, then you will know that this is a job with a lot of future potential. Next, find out a little bit about the person who will actually be your boss if you get the job. Sometimes, this person will be involved in the interview, but often they will not. Finding out how high up in the company chain you will be reporting will help you gauge how important the position for which you are applying is to the company. Also, it helps to know a little bit about the personality type of the boss to be. If you like to keep your head down and do your work, and your potential new boss is one of those “wacky” types, then you may want to look elsewhere. From there, ask about the kinds of responsibilities you will need to take on board right out of the gate. When companies are hiring for a new position, they usually have a few ideas about what that person will need to start working on right away. Getting a clue about your first project will help you decide if this job is right for you. This is also a good time to ask the interviewer about their job and why they like working the company. You may find out that this really could be your dream job, or you may end up sensing from your interviewer that you should run away, fast. Last but not least, ask your interview when you should follow-up on your interview. Don’t open the door for a “don’t call us, we’ll call you” kind of interview closing. Let the interviewer know to their face that will be making the effort to contact them again. You may get the vibe from your interviewer that the job probably will be going to someone else, so you can move on quickly, or you may end up being offered the job on the spot. Either way, you will have opened the lines of communication to take the next step. |
