Technical Notes
StackRadar tracks coarse infrastructure signals rather than user traffic. Public snapshots are intentionally delayed and reduced.
Reduced route samples are compared across short windows to highlight unexpected path changes.
Handshake metadata and endpoint timing are recorded as service availability indicators.
Status class, timeout behavior, and response windows are evaluated by synthetic checks.
Regional deltas are compared against recent baselines for drift and intermittent reachability.
Resolver differences are sampled to isolate lookup timing and answer-set instability.
p95 changes are grouped into event windows for delayed incident timelines.
