Weekly internet health check, US and worldwide

ThousandEyes, which tracks internet and cloud traffic, provides Network World with weekly updates on the performance of three categories of service provider: ISP, cloud provider, UCaaS.

The reliability of services delivered by ISPs, cloud providers and conferencing services (a.k.a. unified communications-as-a-service (UCaaS)) is an indication of how well served businesses are via the internet.

ThousandEyes is monitoring how these providers are handling the performance challenges they face. It will provide Network World a roundup of interesting events of the week in the delivery of these services, and Network World will provide a summary here. Stop back next week for another update, and see more details here.
