KBY Technologies — Production Engineering Intelligence
Configuring Hybrid DNS Conditional Forwarders for Private Endpoints
Systems Architecture // latest analysis
Design resilient systems for production
Explore the latest technologies in software development through senior analysis of enterprise application development, cloud solutions, platform engineering and operational resilience.
Systems Operational
All CI/CD pipelines and production clusters are running nominally.
[System] Listening for incoming technical documentation...
Fresh operational intelligence
The newest Config Trap, incident runbook, Daily Triage drill and Lexicon reference—kept focused on what engineers can use now.
Trace Context Propagation
The standardized way of passing trace and span IDs across service and transport boundaries so spans from different services can be linked into one coherent distributed trace.
IMDSv1 Leaves Role Credentials One GET Request Away
Enforce HttpTokens=required via modify-instance-metadata-options, launch template defaults, and an SCP condition on ec2:RunInstances.
DNS wildcard records (*.domain.com) combined with subdomain delegation causing unintended certificate issuance via ACME
Certificate Transparency monitoring or an internal audit surfaces a valid certificate for a subdomain (e.g. dev.domain.com) issued by an unrecognised ACME account, while that hostname continues to resolve via…
Postgres Logical Replication Slot Stalls After Schema Migration
You’re on call. Read the signals, choose your first intervention, and reveal the reasoning behind every option.
Deterministic engineering tools with explicit contracts.
Explore our deterministic engineering utilities for strict network planning, SLO mathematics, and configuration validation.
SLO and Error-Budget Suite
Calculate exact error budgets, observed SLI and versioned multiwindow burn-rate alert thresholds without floating-point loss.
IPv4 and IPv6 CIDR Planner
Normalize IPv4/IPv6 networks, calculate exact ranges and audit batch allocations for containment, overlap, alignment and unused capacity.
Configuration Validator and Semantic Diff Studio
Validate strict JSON/YAML, apply pinned schemas, generate a verified RFC 6902 patch and fingerprint RFC 8785 canonical configuration.
