DNS Service Consolidation at WHC

Ticket #93 : Consolidation of justingoufo.com DNS Service to WHC

Type : Infrastructure Operation / Simplification
Composants Affectés : Domain Nameserver (NS), DNS Zone

Strategic Objective: To simplify the project's infrastructure by consolidating critical services. The goal was to migrate the DNS service management from Namecheap to WHC (Web Hosting Canada), where the justingoufo.com domain is already registered, in order to reduce the number of providers and centralize configuration.

1. Actions Performed

The migration was executed following a two-step procedure to ensure a controlled transition:

  1. Preparation of the Destination DNS Zone (at WHC):

    • Before initiating any public-facing changes, the DNS zone was configured on WHC's platform.
    • The A records for the critical subdomains (invest and docs.invest) were created, pointing to the static IP address of the application server (147.93.43.173).

  2. Nameserver Update (at WHC, the registrar):

    • The core action of the migration consisted of changing the nameservers (NS) for the justingoufo.com domain.
    • Namecheap's nameservers were replaced with WHC's default nameservers.
    • This change officially delegated the authority for DNS resolution for the domain to WHC.

2. Validation Process

  • The success of the migration was monitored using public DNS checking tools (e.g., dnschecker.org) to observe the global propagation of the nameserver change.
  • Once propagation was confirmed, ping tests were conducted to validate that the subdomains were resolving to the correct IP address.
  • Finally, the web services (https://invest.justingoufo.com and https://docs.invest.justingoufo.com) were tested to confirm their accessibility.

3. Final Outcome

The migration is a success. Both domain management (registration) and DNS resolution management are now consolidated under a single provider (WHC). This simplification reduces administrative complexity, decreases potential points of failure, and aligns the infrastructure with the strategic goal of service centralization.
