When the network says green
and the business says broken
and the business says broken
Between those two signals sits a class of failure most tools never see:
a path or component fails while every health check reports it as healthy. It began in the cloud. It now reaches every network carrying business-critical traffic, and the shift toward AI workloads is widening the gap.
AlvaLinks is the network observability company behind CloudRider and ObservaNet, path-layer probes that detect what the rest of the stack cannot and localize the fault to the segment, hop range, and carrier in seconds.
One measurement engine. Two products, each built for the operations it serves.
Path-Layer Diagnostics
TRUSTED BY GLOBAL LEADERS:
THE PROBLEM
The failure that hides inside a healthy dashboard
Standard telemetry samples the network and reports on what it happens to catch. The failures that matter most live in the space between those samples: partial impairment on a real path, a degraded third-party segment, a route change that resolves before the next poll.
Aggregate metrics average away from what the application feels on the path. And AI traffic compounds it: new load patterns, sub-second delay sensitivity, heuristics that took decades to build and no longer hold. So, the alarm fires long after the event passed, when the root cause is already gone. Until it pops again.
After a series of events closed as "no fault found," a war room forms to find the problems that cost you the trust of users and customers.
Microsoft's research team named this problem Gray Failure in 2017. AlvaLinks is the first to detect it directly.
THE PLATFORM
One engine, two products
Both the ObservaNet and CloudRider products run on a single method: synthetic packets that carry the same signature as your applications' traffic and travel the same path, measured per packet and per millisecond, localized to the offending hop. It's software only, no hardware, and it stays vendor-agnostic and provider-agnostic.
The path-layer probe for enterprises, MSPs, CSPs, and telecom operators.
Customers complain, dashboards stay green, and the root cause analysis (RCA) goes nowhere. The connectivity provider finds nothing. Neither does the cloud provider. ObservaNet localizes the fault to the ISP, SD-WAN, cloud region, transit gateway, or specific hop range, with path-anchored evidence a provider cannot deflect.

The path-layer probe for broadcast and media.
A green dashboard won’t show you the stream that stalls at close, or the audio that turns choppy during the biggest broadcast of the quarter. CloudRider watches the delivery path itself, tuned to SRT, RIST, Zixi, and NDI, and points to the failing segment before audiences notice.
Evidence, in seconds
A series of cloud-provider network anomalies hit Uplynk’s streaming platform. Standard monitoring stayed green. No alarms were fired.
AlvaLinks gives us route-level data, including IPs, paths, and hop-by-hop telemetry, the moment an issue is detected. It changes the conversation with every partner and vendor we work with”
— Shahar Mor, VP of Engineering, Uplynk (March 2026)
That shift, from informed theory to definitive data, is what shortens resolution and holds providers accountable across every network AlvaLinks monitors.
