System status

TKOS Network Status & Live Reliability.

Real-time visibility into every service we operate, backed by a contractual 99.9% uptime SLA, three-region active-active failover between Johannesburg, Europe, and Asia, and a 24/7/365 NOC staffed by tier-3 engineers. This is the same dashboard our on-call team watches.

Live board

Component-level status, refreshed every minute.

Each row below maps to an independently monitored service plane. Health probes run from all three regions and the result rolls up into the indicator you see here — the same one driving our healthcare on-call escalations and tier-3 paging rules.

Live metrics

The KPIs we measure ourselves on.

Numbers below stream from the same Prometheus stack the NOC uses on the wall display. As an ICASA-licensed South African carrier, we publish them in full instead of filtering down to a single uptime percentage.

Recent incidents

Resolved incidents from the last 30 days.

Every incident here was caught by the NOC before a customer opened a ticket. Post-mortems are published per event — the same ones our contact-center partners receive on their MSA addendum each quarter.

    JNB-EU peering brief routing flap

    Secondary peer at the London POP advertised a stale route for 4 minutes. Traffic re-converged via the primary path; no calls dropped on the failover.

  • May 8, 2026Resolved in 12 minUS toll-free DID · provisioning lag

    Toll-free DID provisioning slow

    Upstream registry returned 502s on a small batch of US toll-free orders. We queued, retried, and cleared the backlog without losing any submissions.

  • Apr 27, 2026Resolved in 9 minBulk SMS · throughput degraded

    Bulk SMS queue depth elevated

    A campaign burst from a single partner exceeded the per-tenant rate limit. We expanded the queue, throttled the tenant, and drained the backlog at full throughput.

How we keep it green

Three layers of redundancy, one job to do.

Reliability is built on plumbing, not promises. Here is the architecture that keeps the dots green for our hosted phone system customers even when an upstream peer, a regional fibre cut, or a noisy bulk-SMS partner tries to ruin everyone's afternoon.

Layer 1

Multi-carrier failover

500+ direct interconnects plus tier-1 wholesale peers. Every outbound route has two warm alternates with sub-second BGP convergence — no route, no problem.

Layer 2

Three-region active-active

Johannesburg primary, EU mirror, Asia-Pacific edge. Stateless media handoff means an entire region can drop and active calls keep talking without re-INVITE.

Layer 3

24/7/365 tier-3 NOC

Senior engineers on rotation in Johannesburg — not a first-tier ticket queue. The same people who built the routing logic are the ones paged when it misbehaves.

Status FAQ

Reliability questions, answered straight.

The honest answers about what 99.9% means, how we communicate incidents, and what to wire into your own ops dashboards.

TKOS contractually backs a 99.9% network uptime SLA across voice, messaging, and wholesale VoIP services. Service credits are issued automatically when monthly availability falls below the threshold, with no ticket required from the customer.
