We've identified some Catchpoint monitor types that cannot reliably run on specific nodes due to restrictions imposed by the node's provider. These limitations are beyond our control and are set by the provider's internal policies or local regulations.
While you can still target these nodes for the affected monitor types, the tests will perform inconsistently.
Recommendation: Whenever possible, prioritize targeting nodes connected to different providers other than the below to ensure better or successful test runs.
Known Nodes with Limitations:
| Node(s) | Limited Test Types / Monitors | Details |
|---|---|---|
| These query types are blocked due to the provider's internal policies. | ||
| DNS (all types/monitors) | The policies of ISPs operating in China prevent in-house DNS resolvers from querying the Root Name Servers. | |
| Baghdad, IQ - EarthLink | DNS resolution happening from this node for all the monitors | Due to restrictions imposed by the ISP this node will use the resolver provided by the ISP |
