Also our pricing is straight forward and does not give you any surprises, our texts and even phonecalls are free of charge, you only pay per monitor and user at a minimal fee. 

Best in class Internet Server Monitoring platform.

Don’t be the last one to know your web service is offline or your server is on a spam blacklist or your server is being used to send spam, or loose revenue on your AdWords campaign when your site is down but your ads are running. Our Enterprise level service monitor system is used by large corporations and of course also by ourselves.

With our 1-minute monitoring interval and our open API interface, anything can be monitored and your team will be notified whenever something is wrong by mail, text, phone call or even directly into your ticket system. This is Enterprise class monitoring as used by the Fortune 500 companies. Not only we believe we have the best solution we also have the most affordable one for small to large companies or even individuals who need to monitor their service.

Worldwide monitoring by worldwide coverage

When a site monitor check shows that your site or service is down, we automatically recheck it from other locations before notifications are sent. With multiple check servers in North America, Europe, Latin America, and East Asia/Oceania, you can choose to run your check from any or all regions. 

As our network is rapidly expanding and sometimes changing we provide a full list of current monitoring locations on requests. Feel free to contact our Monitoring Specialists for your questions regarding our monitoring services. 

Service Monitoring is a very important yet forgotten task, even though all hosting providers try to offer you a 100% uptime it is not always possible due to many factors, from hardware to network issues but also content issues which can cause your site to load slowly or not at all. Now you can monitor your SLA with our service monitor tools.

Here at 040Hosting we monitor our services (i.e. CPU, Response times, Mail queues and Connectivity) as well, we even go a step further as 99.9% of the hosts, we do not actually monitor a ping of the servers but rather the actual web server response time for a simple query. This not only tests if the service is online but also if the service is actually responding to what it needs to be doing, serving web pages, accepting email, sending an email and so on. We also check each our managed services in a large list of mail blacklists to see if a shared server or server got blocked so we can take action on such an issue as soon as possible.

Free Unlimited Notifications

Our Service monitor plans do not limit or ask you more money for notifications, we believe that you should always be notified and not be limited by a pre-paid plan on notifications because sooner or later you run out, forget to update your credits and of course, your service did go down just after that. Leaving you in the dark. Not anymore with 040Hosting Monitoring, all your notifications are FREE.

World wide monitoring coverage

Monitoring is not only done from one location, a large spread out monitoring network is needed to provide correct results and to avoid false positives, our monitoring network covers the North American Region, European Region, East Asia/Oceania Region and the Latin America Region. One can choose the region or monitor this site worldwide.

Always up to date

You can monitor your site or services with 1-minute intervals, this way you never miss any event that may disrupt your services. Some non-essential services do fine with five or fifteen-minute intervals, but most businesses need to know if their site is down more quickly than that.

Flexible Server Monitoring

While a ping monitor can be great to see if your server is still responding there are many other ways to monitor your server even better. Our monitoring does not limit you to only Ping or HTTP(S) but can also monitor your SSL certificate, Realtime Blackhole Lists (RBL) or SIP VOIP connections or even build your own application monitoring makes our service the most affordable and complete monitoring solution out there.

Notifications are a key piece of any monitoring service. They are used to alert the correct person, the correct way, so they can react to service interruptions in a timely manner before very many of your customers or users are impacted. We offer Unlimited Free Notifications.

It’s important that every notification sent be ‘actionable’ – meaning it requires a person or system to react to it. Notifications just for information’s sake lead to alert fatigue and your on-call responders begin to ignore notifications because of the noise.

  • SMS
  • Email
  • Pushover
  • Voice Calls
  • Webhooks
  • PagerDuty
  • Slack
  • HipChat

And you can control them by


  • Check Sensitivity and Rechecks
  • Scheduling Notifications
  • Delayed Notifications
  • Notification Dependency
  • Disable All Notifications
  • Time Zone

IPv4 and IPv6 are supported and enabled for almost all locations and monitors, see below for details.

Our RBL and SIP checks do not support IPv6 but all other check types do. Our probes in Latin America do not have IPv6 support (it’s difficult finding IPv6 networks in Latin America) but the rest of our regions fully support it.

Our interval checks go as low as once per minute. 

Some website monitoring companies let you monitor things every five or fifteen minutes, and charge you more if you need more frequent checks. Of course some non-essential services do okay with five or fifteen minute intervals, but most who utilize monitoring need to know if their site is down more quickly than that.

All of our plans include one minute intervals. 

To check that SSL certificates are signed by a valid certificate authority and match the domain.
To receive an alert before SSL certificates expire.

HTTP/S – basic website checker for any URL and on non-standard ports
HTTP/S Content Matching – for deeper website monitoring. This check supports both positive and negative content checks.

HTTP Parse – The HTTP Parse check allows you to monitor, track, and graph arbitrary values provided by a web server. It is commonly used for monitoring and tracking internal server metrics like server load, CPU utilization, available RAM, and disk space. You can build your own application monitoring with this specific monitor.

SSH with response matching, so no longer just check if your SSH port is available, also if it is actually responding.

FTP Service check
FTP File Check

Our FTP check not only alerts you when your FTP service stops functioning properly but will also optionally alert you to the absence or presence of any particular file on the service.


A ping test consists of sending an ICMP echo request packet to a target and waiting for a response. Ping now means more than just the utility, it also can refer to any use of ICMP echo request packets used for the purpose of testing whether a remote host is up and how long it takes them to respond. We only use the real ICMP Ping.

check that a SMTP server is up and responding.
Open relay testing (security)

It’s important to verify that your SMTP servers are up and running but also verify that they’re properly accepting email. We do this by monitoring not only the service but its ability to receive email for particular addresses. If your server uses SSL or TLS to secure mail transport, we can also monitor the functionality and validity of your certificates and send you an alert before they expire.

Check that POP server is up and responding.
To verify a particular user can access email

Check that IMAP server is up and responding.
To verify a particular user can access email

WHOIS Checks should be use to receive alerts before your domain expires. They should also be used to ensure your domain registar has the proper nameservers configured for your domain. You can also use it to verify that your administrative and technical contacts haven’t been tampered with (hijacked).

NTP check requests a timestamp over UDP from your NTP server and waits for a reply.

Use our NTP check when you want to monitor the uptime of your NTP servers or to receive alerts when private servers become publically available, as in the case of a failing firewall rule. The check can be configured to send you notifications if it’s able to get a response or if it’s not able to get a response.

Check that a DNS server is up and responding
Check expected responses

  • To just check that a DNS server is up and responding, just set the DNS Server and port and leave the Query and Response fields blank.
  • To check that public DNS information is correct, leave the DNS Server blank and fill in the Query and expected response. This is useful to make sure that the right information is propagating into the DNS view your customers will see or to find out your DNS has been hijacked.
  • To check that a specific DNS server is responding with the right information to a specific query, fill in all three fields (Server, Query, and Expected Response).

The Port Connect check performs a simple TCP network connect call on any port you specify. It’s protocol agnostic and can be used against any number of TCP network services. It simply reports if a connection was possible or not. The check can be configured to send you notifications if it is able to connect or if it is unable to connect.

The audio check can monitor your Icecast and SHOUTcast audio streaming services to ensure they’re available.

The audio check verifies the HTTP stream is of media type ‘audio’ but does not check for actual audio. Dead air will not cause an audio check to fail.

Our AUDIO check is great at making sure your stream is up and running but until this update we didn’t have a way to tell if the audio playing was dead air. Silence detection is an important part of providing audio streaming and 040Hosting can now send you notifications if your Internet radio, podcast, or other audio stream is playing silence instead of your content.

Our volume detection samples 10 seconds of your stream and computes an average decibel level of the audio. If that detected volume level is lower than your configured threshold (-90 to 0 with a default of -45) your AUDIO check will fail and you’ll receive any configured alerts.

Checks RBL blacklists for your server IP

Operating some shared hosting servers? you really want to keep a check on your RBL listings, this monitoring tool is checking a whole list of RBL servers and warns you when your server IP is on the list, so if you did not act yet, you can now act real soon and minimize the damage.

SIP monitoring can verify that your SIP server is responding to new requests.

The check does not initiate a call, but rather tests that the the server accepts a SIP connection by sending the OPTIONS command and watching for the response. Even if your server does not support the OPTIONS command and returns an error, this indicates that the server is up and operating, so the check succeeds.

The Cluster Check allows you to group interdependent checks in order to get notifications and track availability of the group of checks as a whole, in addition to each component check individually.

WebSocket checks should be used to monitor the availability of WebSocket services.

This check uses HyBi drafts 13-17 protocols for checks starting with ‘ws://’ and ‘wss://’

Currently only versions 0.9.x are supported and the URI must start with ‘http://’ or ‘https://’
