What are Resource Usage Policies?
In hosting environments, a server’s resources are what economists would call a common pool resource, meaning that although having plenty of available system resources benefits everyone, no single user has an incentive to ensure that they don’t use too many resources themselves. In an effort to protect against the tragedy of the (server) commons, we have placed limits on the amount of a server’s resources that any given user may consume. While these are limits, server abuse is not limited to these policies and is up to Blue Signals Hosting discretion what constitutes server abuse.
The Purpose of These Policies
Understand that these policies are in place to protect you, our customers, from poor service quality. Generally, if we need to impose a restriction on an account for resource abuse, that account is in violation of at least two of these policies (or one policy to a very serious degree) and is adversely affecting the other clients on their server. The large, large majority of sites, at least 99.5%, will never even have to take these limits into consideration. That being said, it’s good to make yourself aware of them.
It is also important to note that many of these limits can be seen as “soft” limits. They are not actively enforced, and you can run up to or even over most of them without issue. If, however, you start to affect the overall performance of a server, we do need to have limits and policies in place. Without them it’s incredibly hard to explain to the customer, in quantitative terms, exactly how a site is consuming too many system resources. If an account is found to be in violation of these Resource Usage Policies, we will do our best to work with clients to give 48 hours, 5 days, or 10 days notice depending on the severity of the violation. We reserve the right as outlined in the Terms of Service to suspend a site if it is causing a severe problem.
Unsolicited Bulk/Commercial Email / SPAM
The use of bluesignals.com servers and networks to transmit unsolicited bulk/commercial email (also know as spam) is strictly forbidden. Under no circumstance is the transmission of spam acceptable or tolerated.
The transmission of spam from our servers and networks can cause irreparable monetary and reputation damage. All damages caused by spamming will be prosecuted to the fullest extent of the law.
Any client caught explicitly spamming from our servers or networks will have their account immediately terminated & without notice.

Resource Usage Restrictions
Processes invoked by the web server, cron, shell or any other method should not exceed the following limitations:
- Consume more than 1 GB of RAM.
- Utilize in excess of 5 seconds of CPU time.
- Blue Signals Hosting uses mod_fcgid to manage and serve PHP requests. Each mod_fcgid PHP process is capable of serving one PHP request at a time. Each system user is limited to 3 concurrent mod_fcgid PHP processes.
- Your account as a whole shall not exceed the limitation of daily CPU minutes put forth by us as determined by our accounting software.
- Number of open files should not exceed 64.
- Create core dumps.
- Number of simultaneous processes should not exceed 15.
- Execute a script/binary that forks in a way to create a fork bomb.
- Programs may not run in the background or listen on a network port. If you require a bot, service or daemon, you should consider a dedicated server, as very few shared web hosts allow this type of program.
Blue Signals Hosting makes use of Linux process accounting to determine the amount of resources a user and its processes are consuming; we call this measurement Resource Points. In order to maintain a healthy and reliable fleet of servers, our shared and reseller plans are limited to the following Resource Point limitations are in place:
- Hosting Starter: 250
- Hosting Plus: 450
- Hosting Pro: 600
- Reseller Starter: 1,000
- Reseller Starter: 1,500
- Reseller Starter: 2,000
Graphs showing current and historical usage are available in control panel for review. Legacy plans have similar limits to the numbers above. Please review your graphs for specific Resource Point limitations.
- All users are restricted to 15 concurrent MySQL connections.
- Each database is restricted to 2 GB of disk space.
- Database queries should not exceed 3,000 per hour.
- Database changes (insert/update/delete) should not exceed 1,000 queries per hour.
- Database servers should not be used as a hosted solution. Database access should only be used for the web site hosted by Blue Signals Hosting.
- Remote database access is for administrative purposes only.
Files and Directories
- The total number of inodes in an account may not exceed 75,000. Every file (a webpage, image, email, php file, directory, etc.) on your account uses up one (1) inode. This is not something we actively enforce and it will only become an issue if a client is causing problems for other people on the server. We will of course notify you if this is the case with a full explanation.
- A single log file (such as a ruby production.log) should not exceed 1 GB in size. Total size of all similar log files should not exceed 5 GB in size.
- A directory can not contain more than 2,500 immediate child files. This includes subdirectories themselves, but does not include files contained within those directories.
- Simultaneous Apache connections may not exceed 50 from one individual source at any given time.
- Web processes should not fork or spawn subprocesses.
Email and Mailing Lists
- Each email account is restricted to 10 GB of disk space.
- Processes should not send outbound mail to more than 25 recipients at any given time.
- The maximum number of members per mailing list is 1,500.
- POP connections are limited to 60 per hour.
- SMTP connections (outbound email connections) are limited to 500 per hour per server account.
- Mailing lists larger than 1,500 will require a semi dedicated, VPS, or dedicated server from us. Dividing one list into smaller parts to get around this limit is not allowed.
- Any mailing list over 900 emails is only allowed in off peak times such as Saturday and Sunday or from 1am to 8am local server time during the week.
- Any mailing list must be throttled so that it sends an email every 6 seconds at the very minimum. If the mailing list software you are using doesn’t support throttling you must use something else. We do this as this keeps the server load from going very high and causing problems for other users. If you don’t do this you will be suspended.
- We do not allow you to send to a mailing list you were given or that you bought. This is spamming and we have zero tolerance for this.
- Any mailing list must comply with the rules set forth by the United States of America and can be found at:http://business.ftc.gov/documents/bus61-can-spam-act-compliance-guide-business.
- No Direct SMTP mailing system scripts are permitted. Mail should be relayed through the local MTA.
- All cron jobs must be ‘niced’ to 15 or greater (see the Unix manpage for “nice” for more information).
- A cron job should not execute more frequently than once every 15 minutes.
- Our servers should not be used as an SSH bounce point to other servers/networks.
- You may not use the Unix “find” command recursively on directories more than 5 levels deep.
Dedicated IP Addresses
- Dedicated IP Addresses require valid justification.
- Valid justification includes SSL certificates and DNS nameservers.
On certain web hosting plans, Blue Signals Hosting does not place limits on the amount of particular resources a single client may use. Blue Signals Hosting makes every reasonable effort to provide clients with the disk space and bandwidth resources needed for their websites within the limitations of these Terms of Service. Blue Signals Hosting monitors all servers via automated and non-automated methods to help ensure no single client adversely impacts other clients located on the same server.
Please note that shared hosting plans are for website hosting, and the storage of backups (unless otherwise allowed in this agreement), file repositories, MP3s, videos, photo archives, and similar is strictly prohibited. Violators of this policy may have their accounts terminated.
Failure To Comply With Policy
Failure to fully comply with these terms is grounds for account suspension and/or termination.
We reserve the right to remove any account without prior notice.
