04 / Service reliability

Plan for disruption before it affects the business.

Resilience requires more than a claim of uptime. Enterprise customers need observable service health, incident ownership, recoverable data, tested restoration and clear distinctions between platform capability and contractual commitments.

Context and scope

What this means
in an enterprise review.

Numerish services and add-ons can have different data stores, workloads, regions and third-party dependencies. Recovery expectations must be agreed at that precise service level.

The descriptions below outline control expectations and evidence to evaluate. They do not claim that a specific Numerish product has completed independent certification.

Control objectives

The six areas
to assess.

Each domain brings a specific objective and a practical review item. Choose the level of assurance needed for the relevant service and regulatory context.

DOMAINCONTROL OBJECTIVEREVIEW EVIDENCE
01

Service boundaries and dependencies

Identify the runtime, database, queue, object storage, third-party gateways and customer-managed endpoints required by the workflow.

Request or inspect

Service dependency diagram, environment inventory and critical-path analysis.

02

Monitoring and detection

Define meaningful availability signals, queue delays, API error classes, database health and customer-impact thresholds.

Request or inspect

Telemetry coverage, alert routing, incident classifications and alert test records.

03

Backup and recovery

Verify backup encryption, retention, scope, isolation, restore keys, independent readback and what constitutes a successful data restoration.

Request or inspect

Backup policy, restore-test report, integrity proofs and documented exclusions.

04

Continuity objectives

RTO and RPO should be attached to the service and contract, tested under realistic conditions and reconciled with third-party capacity.

Request or inspect

Agreed SLA/SLO and recovery objectives, disaster recovery plan and tabletop results.

05

Changes and release safety

High-risk updates should follow approval, migration verification, rollback preparedness and separation between UAT and production.

Request or inspect

Release gating records, deployment manifest and rollback/restore evidence.

06

Incident communication

Customers need a named escalation path, incident severity definitions, update expectations and post-incident learning.

Request or inspect

Response runbook, communications terms and anonymised post-incident action evidence where shareable.

Responsibility & acceptance

Clear ownership.
Clear evidence.

The dividing line between supplier capability and customer responsibilities should be agreed before implementation or procurement sign-off.

Customer / governed administration

Your organisation remains responsible for

  1. Identify business-critical workflows and downstream dependencies.
  2. Maintain a customer-owned continuity plan and relevant exports/backups.
  3. Agree recovery targets in the service contract when required.
  4. Test internal procedures for prolonged outage, degraded function and manual fallback.
Scope boundary

There is no live status dashboard or universal uptime/RPO/RTO commitment displayed here unless it is backed by an operating feed or an executed service agreement.

Assurance engagement

Validate the controls
for your environment.

Request product- and version-specific artefacts; identify the relevant jurisdiction, data classes, hosting model and procurement requirements.

Request relevant evidence ↗Documents may be subject to availability, authorisation and confidentiality requirements.
Frequently asked

Important clarifications.

Controls and independently verified outcomes should not be confused.

Does a server backup guarantee every add-on can be restored?

No. A complete recovery requires identifying application state, external dependencies, cryptographic keys, documents and any excluded data. Actual restore tests are the appropriate evidence.

Where can I check whether Numerish is currently available?

This Trust Centre does not claim live monitoring. Request current service status or a contracted incident channel through Numerish support.
