  How much does it cost to store a really big file on your web site? How much more does it cost if the file is downloaded ten times? Find the answers to these and other resource questions using our Resource calculator. Enter a number (including fractional values) in megabytes (MB), gigabytes (GB), or terabytes (TB), select the resource type, and click the Calculate button.

Conserving resources keeps your Internet costs down. By staying within the storage and traffic amounts included with your account, you pay nothing extra.

Disk storage: Your account includes 20MB of free disk space for email and files. Your storage on CTSnet is assessed daily, with amounts over 20MB charged at 2 cents per MB. Use the calculator to determine the daily cost for chargeable storage.    Network traffic: Each month, we include 500MB of complimentary network traffic for use with a web site, FTP Dropbox, co-located server, or CTSnet MediaCast streaming service. Use the calculator to determine the cost for network traffic you generate.





Q: How can my account occupy disk space on CTSnet?
There are two ways your account may use disk space on CTSnet's servers: electronic mail and files. Your online mailbox stores incoming mail until you connect, download, and delete it. File storage is utilized when placing files online (e.g., uploading files into your directory or FTP Dropbox, or when creating content for your web site hosted on CTSnet). In either case, up to 20MB of combined disk usage is provided to you at no charge. Throughout the day you may use and purge more than 20MB of space as needed. But any usage exceeding 20MB at approximately 3AM is chargeable on a daily basis.

Q: How are disk storage charges calculated?
Once a day, CTSnet samples all the disk storage your account is occupying. Your first 20MB of storage is free. The amount in use over 20MB is recorded as "chargeable" disk storage. At the end of the month, your chargeable storage from each day is added up and charged 2 cents per megabyte.

Q: How can I avoid email storage charges?
To avoid storage charges, connect regularly to get your mail and remove it. This is usually an automatic feature of your email software, provided it is configured to remove your email after successfully downloading it. Otherwise email left online will accumulate until you manually remove it from CTSnet's servers. If you need help with this, please contact CTSnet San Diego Technical Support. Caution: If you use CTSnet WebMail or IMAP mail, messages are always stored online until you delete them.

Q: How can I avoid file storage charges?
If you don't have a web site on CTSnet, FTP Dropbox, or a shell account, you need not worry about file storage. But if you do, temporary files should be deleted when no longer required. Care should be taken maintain efficient web page contents. For example, using smaller images or reducing the number of colors in images not only conserves disk space but can dramatically improve download times. (That also translates to less network traffic.)

Q: What is network traffic?
Internet connectivity is like plumbing. The amount of information you can send through a connection in a given amount of time depends on the size. The larger the pipe, the more you can send through it faster (this is called bandwidth). Internet providers like CTSnet maintain extremely large (and as a result, expensive) connections through which all customers access the Internet. Likewise, any access from users on the Internet to CTSnet's servers (on which your web site may be hosted) come through the CTSnet network. It's that access we call network traffic.

Q: When would I be responsible for network traffic?
You are responsible for network traffic exceeding 500MB per month only if you have a CTSnet hosted service such as Personal or Business Web Publishing, FTP Dropbox, Server Co-location, or MediaCast streaming service. These services are all capable of generating network traffic when Internet visitors access your online content. If you don't have any of those services, you can surf the web, access streaming media, and download files and not be concerned about network traffic charges.

Q: How is network traffic measured?
Network traffic is measured in bytes, a basic unit of character data. 1024 bytes is one kilobyte (KB). 1024 kilobytes is one megabyte (MB). 1024 megabytes is one gigabyte (GB). And 1024 gigabytes is one terabyte (TB). (There are measurements beyond that, but that's generally high enough for most people). Each time files (perhaps a web page and all its objects) are sent to a browser, the number of bytes are recorded.
