xAI API endpoint
Measurement point: Stealth NYC, 32 Avenue of the Americas.
Published investigation. Updates run automatically.
Successful endpoint RTT recordings from up to one hour before and after the event.
Times use the selected timezone; choices include recorded samples and intervals across the available chart.
05 Nov 2026 15:00 – 05 Nov 2026 17:59 UTC. Hover or tap to inspect; drag across the chart to zoom. On touchscreens, first choose Select time range. Escape or Reset zoom restores the full range. Missing recordings are gaps; this is not an application availability or packet-loss chart.

RTT is the round trip to each responding hop, not the delay of the preceding link. TTL order may omit routers and does not prove direct links. A missing reply is not proof of packet loss. ASN labels are dated address associations; they do not establish the forwarding path or the operator at the event time. Up to three recorded traces per method and period are selected across the archive. Where no individual trace is available, a comparison may summarize a window; MTR observations aggregate multiple probes. Address aliases are independent across measurement types.
Compare one selected trace from before the event with one during it. Values are individual replies, not a statistical comparison.
Before: UTC · During: UTC

|---|---|---|---|
| 1 | 0.218 msAS8002 · Stealth | 0.547 msAS8002 · Stealth | Same responder |
| 2 | 0.215 msAS8002 · Stealth | 0.187 msAS8002 · Stealth | Same responder |

RTTs include the return path. Different responders, missing replies and independent probe flows limit what a change can localize. MTR snapshots remain separate in the replay.
Latency anomaly. Times shown are UTC.
Recorded recovery describes this event, not current reachability.
Endpoint round-trip time was elevated during part of the event. The available path observations do not identify where the increase occurred.
Recording counts describe collected measurements, not application availability or packet loss. Exact packet paths and the return path remain unverified.
RTT is round trip time; p95 describes the upper range of successful recordings. Endpoint measurements differ from individual trace replies and are not an uptime percentage.
Event and source timestamps are UTC. The latency chart uses its selected timezone. Page refresh times are separate from measurement timestamps.
Comparisons use matching destinations before and during the event. ICMP traces use echo probes. TCP/443 traces send SYN probes to port 443 only; they do not complete a TCP handshake or perform a TLS or HTTP exchange.
The Stealth gNMI interface verifies the active route-table choice and maps its primary next hop to the Stealth logical interface, configured attachment and, where applicable, the known LAG member set at each snapshot. Stable Stealth replies, together with mapped interface evidence showing no corresponding errors or sustained capacity pressure, reduce the likelihood of a Stealth forwarding issue. An 80% load warning warrants investigation; it does not prove congestion. Lower interval averages can conceal bursts or queue pressure. Optical readings assess the physical link, not congestion.
Probe reply handling can differ from packet forwarding. A slow intermediate reply that disappears at later hops does not locate a forwarding problem. A destination that does not respond to a trace is not thereby shown to be unavailable.
Stealth does not use ECMP in this monitored scope. The route snapshot does not identify which physical LAG member carried a particular independent probe, attest line-card forwarding at that packet instant, prove the exact application packet flow or observe the return path. RTT includes the return path, which may differ. No remote reverse traceroute is available. Tunnels and silent routers may hide parts of the path. Address registration alone does not establish the forwarding operator or responsibility.
