Uptime
Uptime Uptime is the period of time when a site performs well.

Uptime corresponds to the time when a site is accessible from the Internet. The opposite term - downtime - shows for how long a site has not been working during specified period of time. Usually uptime is measured in percents, and for period of time is choosen year. Percents over the year could be easily transformed into time values. Some typical values of uptime and corresponding period of unavailability during the year are shown here:

90% - 876 hours

99% - 87 hours, 36 minutes

99.9% - 8 hours, 45 minutes, 36 seconds

99.99% - 52 minutes, 34 seconds

So high uptime is really important. Even if it seems that 99% is pretty high value - it corresponds to several days of failure. If that happens in a row, many clients can be lost. Uptime value is usually guaranteed by web hosting, where the site is hosted. Website Monitoring may help you to increase the uptime and check if the value, declared by the hosting company, is real.

Blacklisted again? Why does this keep happening to me?!

We’re happy to announce that this tool has just got even more awesome! Now you can use our DNSBL check tool as a one-time job or on a regular basis. It means you can keep your IP address in a continuous check against dozens of the most popular blacklists. 

Previously, we have introduced one of the “Check site instantly ” board functions -  DNSBL - which helps you find out whether your server is blacklisted before it gets out of control.

We’re happy to announce that this tool has just got even more awesome! Now you can use our DNSBL check tool as a one-time job or on a regular basis. It means you can keep your IP address in a continuous check against dozens of popular blacklists. 

This can significantly ease your website’s life online, moreover, bring balance into it.

New options

With the new extension of the DNSBL check tool, it's become easier to test your website accessibility, as well as, server message deliverability.

For example, suppose your IP address is currently on the DNSBL monitoring. The moment your website is found blacklisted, our system will report back to you all the detailed information on the check results - the name of the blacklist (which one of the DNS-based anti-spam lists recognize you as a source of spam activity) and the reason for listing (this information is public and provided directly by DNSBL databases).

All this will allow you to quickly clean up “the mess”, speed up the process of domain removal (delisting), protect your business reputation and, by extension, prevent recurrence of such a problem in the future.

HostTracker, as a website monitoring service, always keeps moving forward - our list of DNSBL servers is constantly updated.

The whole setup process will take you only a few minutes to complete:

Some Secrets of Activating Blacklist Monitoring

The good news is that you’re opted to activate the DNSBL check for already existing monitoring tasks. All you need to do is to put a tick mark in the box next to “DNSBL check” field when editing or adding a check task.

Once enabled, HostTracker starts gathering information about your website availability and checking whether your IP is currently listed. A Contact Group for notifications will be automatically added to the current test task. If our system finds your server blacklisted, you’ll immediately receive a message with the relevant information.

We hope that with such a tool you’ll enjoy the convenience, simplicity and quality of our all-in-one monitoring service. If you have any questions or suggestions, feel free to contact us - we’re always looking for ways to improve!

Home > FAQ > monitoring
Can I insert a list of sites for monitoring?
While creating a new monitoring task click "Add list" near the URL field. Then insert into the extended field the list of sites, each one from the new line.
How to add more sites for monitoring?
Sign in at www.host-tracker.com and on the main page and click "Add", for web sites click on http. Then fill regular task creation form.
Does HostTracker affect my analytics?
HostTracker does not execute any javascripts while checking your sites. So, if you use external monitoring tool, like Google Analytics, these checks are not counted. However, if you use some internal monitoring system - HostTracker requests will be logged. In this case you may exclude checking servers by IP. List is here.
How to check CONTENT with HostTracker?
Visit this link for detailed instructions: Content Check.
Does HostTracker support HTTPS monitoring?
Yes, HostTracker has full https support. Certificate-related errors are reported as well as usual http error codes.
Where can I find the list of HostTracker IPs?
IP addresses of all HostTracker servers are in this list. Note that the list may change over the time, as HostTracker network grows.
I set my site to be checked every 1 (10, 30 etc) minutes, however I see only 1 record in logs for a day. Why?
Note that adjacent checks with the same result (all show Ok or all fail) stack into a single record in logs by default. Pay attention to columns "Check cnt." and "Interval" in the log. "Check cnt." shows how many checks have been made for the specified interval. It is done to make logs less bulky. However, you may turn on "Full log" option for your tasks - in this case all checks are saved separately. You may select this option while creating or editing a task.
