A quick gimmic to get users to host with them. Similar to the "free domain" offers of years past (which were actual VALUE).
Overselling is accepted by many people and is considered "good practice" by many hosting companies. Personally, overselling is taking users resources and giving them to someone else. It's like renting a limo for the night, paying $65/hour, and just because you're inside at an event for 4 hours, that doesn't mean they get to take the limo and do other things. I PAID for that time - sit outside!
I don't believe in overselling (disk or bandwidth). Many hosts DO and it's almost accepted these days, but in my opinion you're giving resources that were allocated for user "X" and selling them to user "Y" just because user "X" hasn't used them yet.
That's a level of overselling that may indeed be hard to sustain, but it's not where overselling starts.Come on, you will never get to use 300GB space, 1TB bandwidth for $3.95 per month!
I believe that overselling is a marketing gimmick. We would naturally like to get more for less, so many people are duped by these offers.
I don't believe in overselling as it might (and probably will) put a strain on server resources, and if someone really uses what they need on the oversold plan, server performance will be greatly affected, making people angry and making you lose business.
Realistically almost all webhosts "oversell" disk space the same way airlines over book flights. Very few sites use even close to the multiple gigabytes of bandwidth that come standard with even the cheapest accounts. If every account on a given shared hosting server maxed out it's disk quota, the hard drive would be full.
Back when I worked tech support for a host, I ran some statistics across all their shared hosting servers and found that the average site only used 5% of it's disk space quota. I imagine this is still true.
This said, offering unlimited resources is dishonest, especially considering the ToS that detail conditions for terminating said "unlimited" accounts usually due to CPU usage.
what do you think about bandwidth , disk space overselling of top hosting companies ?
The oversold customers that legitamately use 500GB storage and 25TB bandwidth would cost a host thousands a month, but all the customers who use 5MB storage and 100MB bandwidth make hosts like Bluehost millions a month.
I wonder if companies like Bluehost do have customers that use X,xxx-XX,xxx GB of bandwidth every month and if those customers are indeed "untouched" by the company.
It would seem that "managing overselling" is company's ability to kick off and terminate those customers that start using the resources included in their plan. Its a game of muscle - a multi-million dollar company with many lawyers versus an average webmaster.
