Ping (ICMP)
Ping (ICMP) Ping is request message for protocol ICMP.

Ping is request message for ICMP (stands for Internet Control Message Protocol). This protocol is used by different network devices to check if a service or a device is available. Usually it is used for network diagnostics.

Ping monitoring allows you to keep an eye on your network infrastructure. Ping failure means broken connection to a network entity. It is handy to use Ping together with HTTP monitoring. In this case, you get additional information - for example, you know if the error is site-related, or the whole server has gone down. However, sometimes ICMP could be blocked for incoming requests, in order to prevent ddos attacks.

"Thank you so much for your service. We were suspecting problems with our hosting company but they denied any problems saying the issues must be at our end. We know we do have issues at our end but still suspected that wasn't the entire story. Your service was able to prove that they are indeed going down regularly - on average twice a week during the trial period. Thanks again for providing the information we needed to make a proper decision on this issue."

HostTracker — Sites Monitoring Service

Every site owner knows how important it is to have your resource always operative and available for visitors. Periodical site unavailability has a bad influence even at its positions in the search engines (as Google representatives have repeatedly claimed), not to mention the fact that visitors are extremely displeased by such “accidents”...

How to be always aware of how properly your site is operated in real time?

HostTracker is an online website monitoring service, having rich functionality and good feedback of the customers, who are, by the way, more than 25 thousand (including the resources of such companies as Colgate, KasperskyLab, Panasonic etc.).

The job design of this service is the following: at certain specified intervals your websites and servers will be checked for availability and serviceability (the verification is performed from around the world), and in case of any problems you will receive notifications about the problems. In addition, uptime statistics for each site is collected, but it will be discussed later.

A quick site serviceability check may be performed directly from the service main page through typing its address in the upper right window and selecting one of the verification methods:

  • Http – website pages loading check
  • Ping – the server availability check (pinging)
  • Trace – the server availability check (tracing)
  • Port – random server port check

According to the check results a detailed report will be created on a separate page.

To become the HostTracker service client and verify the uptime and serviceability of your resources on a regular basis you need to register in the system and assign the appropriate tasks. Over time detailed statistical reports and visual graphics will be created for each task, greatly facilitating data analysis, outputing them in an understandable representative form.

Site failures and problems may be reported to (at your option):

  • Email as a letter
  • telephone as an SMS or a call
  • Skype or GTalk as a message

At that it is possible to set the notifications delay, their uploading time etc. – the settings are very flexible. By the way now I really miss such functionality at Monitorus, as it sends an SMS immediately when a problem occurs, regardless of the time of day, and as you can imagine, late night may be very fun because of this).

Another useful feature of the HostTracker service is the site content monitoring. You may set a list of the page keywords, at the disappearance of which you will receive the notification. Or vice versa – set a list of words, at the appearance of which you will receive the notification. The first case, for example, is good for paid links on other sites monitoring, and the second – to prevent virus activity in the form of additional code embedding on your website. Say, it is very helpful and very convenient!

Now a few words about the HostTracker site monitoring service rates prices. There are several service plans, differing in the maximum tasks number, check frequency, etc. However, there is also a full-featured trial period of 30 days, as well as the Free tariff, within which you may monitor up to two resources with an interval of 30 minutes. That’s not much of course, but as an option to try out all the features for free, and then decide on the appropriateness of the paid tariff transition, it is just the job. Good luck!

Anyone can be blacklisted – so what can you do? How can you detect such problem? Are there any protection mechanisms? This is what this article is about.

Are you sure that your domain isn’t currently listed with some anti SPAM-database? We recommend you to check this out!  As you can be one of those who accidentally fall into being blocked due to spreading spam, malware, viruses or just having dangerous, illegal or prohibited content (links to such content) hosted on their pages. Apparently, anyone can be blacklisted – so what can you do? How can you detect such problem? Are there any protection mechanisms? This is what this article is about.

Why is this happening?

There are tens of thousands of different DNSBL-servers up for grabs out there and they all have their own set standards and criteria for which IP should be blacklisted. Moreover, these conditions are constantly changing. Therefore, there’s no guarantee that even a law-abiding domain which meets all standards of copyright and trademark laws, the laws of privacy and publicity, and other applicable regulations and statutes of law, one day wouldn’t be filtered out by the search engine as one that spreads spam.

Actually, HostTracker’s team recently faced the risk of being banned too. HostTracker, in its capacity as a website monitoring service, sends daily many various reports to the people that requesting them, hence it was easy to determine that some of our emails hadn’t been delivered and were dumped into a spam folder.

So what should you do?

Understanding the problem is the first step to fixing it. So it’s crucial to be aware of the warning signs of listing threat and be able to quickly take steps to cut back if you recognize them. Since we recommend adopting our new feature - "DNSBL" on the "Check site instantly" bar - we have implemented just for you:

This option is not exactly brand new, as there are dozens of different check services out there (for instance, Mxtoolbox), which offer a convenient help in testing whether your domain is on some blacklists. But soon we realized that we also needed to arm HostTracker with this check, as without having had such tool in place, we were flying blind.

In light of what was written above, we provide the illustration of how the "DNSBL" check works:

If HostTracker detects some suspicious activity from your IP address, you’ll be notified immediately with an alert of a possible listing reason. For you it means - the ability to track the reason why the site was blocked to its origins.

Usually, the domain will be blocked not at once but only after a thorough analysis of many factors. If you have already discovered your IP on one or more blacklists, don’t panic, more often than not, all you need to do is to follow their specific removal process. That implies, you should visit the corresponding blacklist's website and, following the removal instructions, enter the domain name and press "Delist". Additionally, you may need to contact the blacklist with a removal request. Note that, previously you have to resolve all issues that caused the blacklist.

So, if you happen to discover your IP address involved in spamming – resolve the underlying issues and you’ll be removed automatically, once a certain period of time elapses. How to stay protected and off of blacklists? The best option is to use PTR or SPF for messaging, as this’ll eliminate the likelihood of your domain name getting fraudulently spoofed and abused by spammers, or blocked for appearing to use a dynamic IP address.

There's no single cause of being blacklisted. Generally speaking, if your IP has been tagged illegal accidentally, the removal process won’t take much time and effort. But it is essential to be proactive, so that to be able to act fast and be in tune with such situations. The sooner you find out about the issues, the easier they are to deal with and the more likely that your domain name won’t be deemed illegal among the entire set of DNSBL databases. Use our new option "DNSBL" on the "Check site instantly" bar to be always aware of the "status" of your resource and never be tossed and turned by the tides of website hassles and outages. Remember, we’re looking forward to any interesting comments and suggestions regarding our service and its work.
