A content delivery network serves resources from distributed infrastructure. Different services can use different endpoints and routes, so one fast website does not establish that the media path is equally healthy. Compare the affected stream directly.
Understand the shared and separate parts
Your Wi-Fi and access line may be common to both services, while the later internet route differs. Success elsewhere narrows the investigation but does not identify exactly which upstream component is responsible.
Keep comparisons controlled
Test the same media source over a supported wired connection and, if appropriate, another authorised access path. Record time and location broadly. Do not publish account-bearing URLs to crowdsource route testing.
Give support useful evidence
Report whether the issue affects only one source, all sources on the service or unrelated services too. That scope helps distinguish a local problem from an endpoint or routing issue without guessing which company's network is at fault.
