How Multiple Server Hosting impacts your website's uptime by: Godfrey E. Heron

This article describesrepparttar technology behind multiple server hosting and how you may utilize it to maximize your site's security and uptime.

Hosting of websites has essentially become a commodity. There is very little distinguishing one hosting company fromrepparttar 142037 next. Core plans and features arerepparttar 142038 same and price is no longer a true determining feature. In fact, choosing a host based onrepparttar 142039 cheapest price can be more expensive inrepparttar 142040 long term with respect to reliability issues and possible loss of sales as a result of website downtime.

Selecting a host fromrepparttar 142041 thousands of providers and resellers can be a very daunting task, which may result in a hit and miss approach. But although hosting may have become a commodity, one distinguishing feature that you must always look out for is reliability.

If you don't knowrepparttar 142042 uptime of your site, or its performance level, try a website monitoring service.

Atrepparttar 142043 heart of any hosting company's reliability is redundancy. This ensures that if a problem exists at one point, there will be an alternative which ensures continuity as seamlessly and transparently as possible.

Most hosts do employ redundant network connections. These arerepparttar 142044 high speed pipes that route data fromrepparttar 142045 server to your web browser. But, redundant 'multiple web servers' have been extremely rare and very expensive, requiring costly routing equipment which has previously been used only in mission critical applications of Fortune 500 companies.

However, a very neat but little known Domain Name Server(DNS) feature called 'round robin' allowsrepparttar 142046 selection and provision of a particular IP address from a 'pool' of addresses when a DNS request arrives.

To understand what this has to do with server reliability it's important to remember thatrepparttar 142047 Domain Name Server (DNS) database maps a host name to their IP address. So instead of using a hard to remember series of numbers (IP address) we just type in your web browser, to get to your website.

Now, typically it takes at least 2 to 3 days to propagate or ‘spreadrepparttar 142048 word’ of your DNS info throughoutrepparttar 142049 internet. That's why when you register or transfer a domain name it isn't immediately available torepparttar 142050 person browsingrepparttar 142051 web.

This delay has stymiedrepparttar 142052 security benefits of hosting your site on multiple servers, as your website would be down for a couple of days if something went awry with one server. You would have to change your DNS to reflect your second server and wait days beforerepparttar 142053 change was picked up in routers onrepparttar 142054 internet.

Title ----- YAWNA - Yet Another Wireless Networking Article Wireless Network Security ------------------------------------------------------ The consumer-level wireless networking market has exploded overrepparttar 142010 past few years. Unfortunately, manufacturers have been lax in explainingrepparttar 142011 potential security risks associated with their products. Typical instructions bundled with consumer products are geared towards getting you up and running as quickly as possible. Only recently has consumer equipment begun shipping with basic security measures enabled. Unfortunately, this effort is flawed byrepparttar 142012 fact that all devices typically ship withrepparttar 142013 same default configurations, makingrepparttar 142014 effort wasted.

Do People Really Care About Wireless Security -------------------------- While there are hundreds, if not thousands, of articles currently available on how to secure a wireless home network, they frequently address onlyrepparttar 142015 steps involved, ignoringrepparttar 142016 reasoning behind them. Of courserepparttar 142017 most obvious reason is to protectrepparttar 142018 data on your own network. Believe it or not, many people don’t see this as enough incentive. One of my own family members (who has an IT background, no less) once expressed to me thatrepparttar 142019 security of his network wasn’t of concern because he knew his individual machines were safe. He was right with regards to his systems; they were pretty secure. However, his belief that someone intruding on his network was there for his stuff was flawed.

Using Your Wireless Network For Fun & Profit ----------------------------------- Your bandwidth alone is a significant motivator forrepparttar 142020 less than scrupulous. Your unsecured wireless network can provide repparttar 142021 ultimate “anonymizer” for illicit activities. You may be facilitating a glorious “hacker” techno-battle, such as those portrayed inrepparttar 142022 movies and television. Perhaps an international spy needs to transmit secret data back to her superiors and decides to borrow your network to fulfill repparttar 142023 task. While not likely, you never know. Little Johnny Wants A New Toy ---------------------------------------------- Here’s a more realistic scenario:

Little Johnny has a stolen credit card number. We don’t know how he got it, it doesn’t really matter. What does matter is that Johnny now wants to take advantage of his prize and knows exactly how. His reward will be one of those new handheld video games that are flying offrepparttar 142024 shelves. Johnny isn’t foolish enough to walk into a store and use his stolen credit card, he knows a better way. Johnny lives acrossrepparttar 142025 street from you and your unsecured wireless network
