The Internet has many moving parts: routers, switches, hubs, terrestrial and submarine cables, connectors on the hardware side, and complex protocol stacks and configurations on the software side. If something goes wrong that slows down or disrupts the internet and impacts your customers, you want to be able to locate and understand the problem as quickly as possible.
new map
The new Amazon CloudWatch Internet Weather Maps can help. Built on a collection of global monitors operated by AWS, you get a broad, global view of internet weather, and can zoom in to understand performance and availability issues impacting specific cities. To access the map, open the CloudWatch console and network monitoring Click on the left side, internet monitor. A map will be displayed and the weather around the world will be displayed.
Red and yellow circles indicate ongoing issues that impact availability or performance, respectively. The gray circles represent issues resolved within the last 24 hours, and the blue diamonds represent his AWS Region. Leave the map on the screen and it will automatically update every 15 minutes.
Each issue affects a specific metropolitan network that represents the combination of where clients access AWS resources and the Autonomous System Number (ASN) used to access the resources. An ASN typically represents an individual Internet Service Provider (ISP).
The list on the right side of the map shows active events at the top, followed by recently resolved events going back 24 hours.
Hover your mouse over either indicator to see a list of city networks within your geographic area.
Zoom in a step or two and you’ll see that these city networks are spread across the United States.
Zooming in further reveals a single city network.
This information is also available programmatically.new ListInternetEvents This function returns up to 100 performance or availability events per call. Optionally filtering by time range or status is also possible (ACTIVE or RESOLVED),or (PERFORMANCE or AVAILABILITY). Each event includes complete details including latitude and longitude.
The new map is accessible from all AWS Regions and there are no usage fees. We have many powerful additions coming to our roadmap, which will be prioritized based on your feedback. Currently we are thinking about the following:
- View the causes of specific types of outages, such as DDoS attacks, BGP route leaks, and route interconnect issues.
- Add views specific to the selected ISP.
- View the impact on public SaaS applications.

CloudWatch Internet Monitor
The information in the map applies to anyone using applications built on AWS. If you want to understand how internet weather affects your particular AWS application and take advantage of other features like health event notifications and traffic insights, you can take advantage of CloudWatch Internet Monitor. My colleague Sebastian wrote this when we launched this feature at the end of 2022:
One of the challenges in monitoring internet-facing applications is collecting data outside of AWS to understand how the application performs for customers connecting to multiple geographically dispersed internet providers. You mentioned that the key is to create a realistic situation in which it will work. Capturing and monitoring data about Internet traffic before it reaches your infrastructure can be difficult or very expensive.
After checking the map, you can click on it. Creating a monitor To start CloudWatch Internet Monitor:
Then, enter a name for your monitor, select the AWS resources you want to monitor (VPC, CloudFront distribution, network load balancer, Amazon WorkSpace directory), and select the desired percentage of internet connection traffic to monitor. The monitor starts working within minutes and uses entries from your VPC flow logs, CloudFront access logs, and other telemetry to identify the most relevant city networks.
