Network monitoring is more than just "UP" and "DOWN" alerts...

Use our monitoring services to pinpoint weakness in your infrastructure, hit performance goals, and troubleshoot connectivity barriers.

How It Works

Monitoring Checks


Interval: Checks can be run as often as every 30 seconds

Check Regions: Choose from five different regions. You can also pick specific sites.

Contact Groups: Make sure the right person or team is alerted when your check comes back as down.

Notification Report: Contacts will receive an email with a link to a detailed report of the latest check activity. These reports expire after a specified length of time.

Interval Policy: Run checks simultaneously across all regions/sites, or rotate through each site.

Verification Policy: If one site is down, Sonar will check a nearby site to verify that the issue is localized or widespread.

Alerts Built for Teams

Make sure the right person is alerted at the right time.

Our team took our 15 years of monitoring our global network to engineer a monitoring service just for network admins.

Alerts can be customized by:

  • Contact Groups
  • Contacts by Role, ie: NOC, SysOps, Support...
  • Shift Schedules
  • Regular Maintenance Windows

Analyze how different website components can affect load times.

Real-User Monitoring  

See your network from the perspective your users. Get a granular as: browser type, Wi-Fi connection, device, ISP, or location.

Response Times

View a quick snapshot of recent response times from all check locations. Data is updated in real time and can be exported as a raw data file.

Status Codes  

Great for web developers and designers! Make sure your website is loading across multiple protocols, verify HTTPS certifications, and monitor load times.

Troubleshoot common network issues step by step with our free wizard. Install the extension in your browser (Chrome only), enter your domain, and we'll do the rest!


Sometimes, the best way to troubleshoot is to test your network the way your users would use it. Run traceroutes from dozens of different locations in our network and compare them to past traces.

Coming soon! Sonar intelligence will alert you if traceroutes vary beyond the norm, ie: latency, extra hops, etc.


Automated Solutions Integrated with Monitoring

Enhanced Failover

All Failover decisions are informed by real-time information from our Sonar monitoring beacon. As soon as an IP is offline or underperforming, DNS automatically moves your traffic over to your backup IP. Sonar then monitors your old IP and will failback your traffic when it becomes available.

Validate SLA's

Our monitoring checks are great for SLA validation. Enable alerts and always know when one of your service providers is down or underperforming.

Multi-Vendor Load Balancing

Don't limit yourself to just one cloud provider. Diversify your routing to get the best price points and services from each provider.

Seamless Migrations

Effortlessly migrate your existing infrastructure to the cloud or create a hybrid network with no performance degradation.

Slash Load Times

Users have come to expect sub two second load times. ITO makes it easy with automated CDN balancing based on real-time performance metrics.

Since you are steering your traffic at the DNS level through your hosting provider, there are no extra lookups required. This can save your valuable milliseconds and is more efficient than third-party or application-level solutions.
