What Is DNS Cutover? A Clear Guide for Nepali Payment-Ready Sites
DNS cutover is the crucial final step in any website migration, involving the precise updating of your domain's DNS (Domain Name System) records to direct traffic from your old hosting server to your new one. This ensures that your website, email, and especially your payment gateways like Khalti, eSewa, and bank transfer integrations, remain fully operational and accessible to your Nepali customers throughout the transition.
Key facts: * Definition: The act of changing DNS records to point a domain to a new server. * Purpose: Ensures seamless website and service availability during hosting migration. * Impact: Affects website loading, email delivery, and online payment processing. * Key Records: A records (IP address), MX records (email), CNAME records (aliases). * Propagation Time: Can take 24-48 hours globally, but often faster within Nepal. * Crucial for: Nepali businesses relying on Khalti, eSewa, and bank transfer for transactions.
Understanding DNS and Its Role in Website Migration
Before diving into the 'cutover,' it's essential to grasp what DNS is. The Domain Name System acts like the internet's phonebook, translating human-readable domain names (like hostingnepals.com) into machine-readable IP addresses (like 192.0.2.1) that computers use to locate websites. When you type a website address into your browser, your computer queries DNS servers to find the correct IP address, then connects to that server to load the site.
The Importance of DNS for Nepali Payment Gateways
For Nepali businesses, especially those leveraging local payment solutions like Khalti, eSewa, and direct bank transfers, a smooth DNS cutover is non-negotiable. If your DNS records are not updated correctly or propagate slowly, your customers might experience issues accessing your website, leading to failed transactions or an inability to complete purchases. Imagine a customer trying to pay for a product using Khalti, only to find your site unreachable – this directly impacts your revenue and customer trust. According to a 2025 report by the Nepal Telecommunications Authority (NTA), over 60% of online transactions in Nepal now rely on digital wallets or direct bank transfers, highlighting the critical need for uninterrupted website access.
When you migrate your website to a new hosting provider, such as Hosting Nepal, your website files and database are moved to a new server with a different IP address. The DNS cutover is the process of updating your domain's A record (which maps your domain to an IP address) to point to this new server. Without this update, your domain would still direct visitors to your old, now empty, server.
The DNS Cutover Process: What Happens Behind the Scenes
The DNS cutover isn't a single, instantaneous event but a process involving several steps and a period known as DNS propagation. During this time, changes made to your DNS records are updated across DNS servers worldwide. While internet service providers (ISPs) like WorldLink, Vianet, Classic Tech, and Subisu in Nepal typically update their caches frequently, global propagation can still take up to 48 hours, though it's often much faster.
Key DNS Records Involved in a Cutover
Several types of DNS records are crucial during a migration and cutover:
* A Record (Address Record): This is the most important record for your website. It maps your domain name (e.g., yourdomain.com.np) to the IP address of your web server. During a cutover, you'll update this to your new hosting provider's IP address. * MX Record (Mail Exchanger Record): These records specify the mail servers responsible for accepting email messages on behalf of your domain. If your email is hosted with your web host, you'll need to update these. If you use a third-party email service (like Google Workspace or Zoho Mail), these usually remain unchanged. * CNAME Record (Canonical Name Record): These records create an alias from one domain name to another. For example, 'www.yourdomain.com.np' might be a CNAME pointing to 'yourdomain.com.np'. * TXT Record (Text Record): Often used for verification purposes, such as proving domain ownership for SSL certificates or email authentication (SPF, DKIM). These might need updates depending on your new host's requirements.
Preparing for a Smooth DNS Cutover
To minimize downtime and ensure your payment-ready site continues to function flawlessly, proper preparation is key. Hosting Nepal recommends a systematic approach:
1. Backup Everything: Before initiating any migration, create a full backup of your website files, database, and email accounts from your old host. Many hosts, including Hosting Nepal, offer cPanel backup tools that simplify this. This acts as a safety net if anything goes wrong during the WordPress migration or data transfer. 2. Migrate Website Files and Database: Transfer all your website data to the new hosting environment. For WordPress sites, this often involves moving files via FTP or cPanel's File Manager and importing the database. Hosting Nepal provides free migration assistance for cPanel transfers, making this step hassle-free for Nepali businesses. 3. Test Your Site on the New Server: Before changing DNS, you can often preview your website on the new server using a temporary URL or by modifying your local hosts file. This allows you to verify that everything, including your Khalti and eSewa payment integrations, works perfectly on the new server before going live. 4. Lower Your DNS TTL (Time-To-Live): The TTL value dictates how long DNS resolvers should cache your records. A high TTL (e.g., 24-48 hours) means changes take longer to propagate. Temporarily lowering your TTL (e.g., to 300 seconds or 5 minutes) a day or two before the cutover can significantly speed up propagation once you make the change. This is a crucial step for minimizing downtime for your online store in Nepal.
Executing the DNS Cutover and Post-Migration Checks
Once your website is fully transferred and tested on the new server, and your TTL has been lowered, you are ready for the actual DNS cutover.
Updating Your Nameservers or A Records
There are generally two ways to perform a DNS cutover:
* Changing Nameservers: This is the most common method when moving to a new hosting provider like Hosting Nepal. You update your domain registrar (where you registered your .np or .com.np domain) to point to the new host's nameservers (e.g., ns1.hostingnepals.com, ns2.hostingnepals.com). The new host then manages all your DNS records. * Updating A Records: If you prefer to keep your DNS management with your domain registrar or a third-party DNS service, you will simply update the A record (and potentially MX, CNAME, etc.) to point to your new hosting server's IP address. This method gives you more granular control over individual DNS records.
After updating, monitor the propagation using online DNS lookup tools. While global propagation can take time, users in Nepal connected to local ISPs might see the changes much faster. "On average, users in Kathmandu experience DNS propagation within 2-4 hours for major ISPs," states a 2026 industry analysis by Marketminds Investment Group.
Post-Cutover Verification for Payment-Ready Sites
Immediately after the DNS cutover, perform thorough checks:
* Website Accessibility: Clear your browser cache and access your website from different devices and networks (e.g., mobile data, different Wi-Fi providers like WorldLink, Vianet). Ask colleagues or friends in different locations in Nepal to check as well. * Payment Gateway Functionality: Crucially, test your Khalti, eSewa, and bank transfer payment integrations. Make small test purchases to ensure transactions process correctly. Verify that confirmation emails are sent and received. * Email Functionality: Send and receive test emails to and from your domain to confirm MX records are pointing correctly and email services are operational. * SSL Certificate: Ensure your SSL certificate is correctly installed and active on the new server, showing HTTPS in the browser address bar. This is vital for securing payment data.
Troubleshooting Common DNS Cutover Issues
Sometimes, issues can arise during or after a DNS cutover. Common problems include:
* Website Not Loading: This is usually a propagation issue. Wait a few more hours and recheck. Ensure your A record points to the correct IP address. * Email Not Working: Verify your MX records are correct. If you changed nameservers, ensure your new host has correctly configured your email service. * Mixed Content Warnings: If your SSL certificate is active but some parts of your site load over HTTP, you might see mixed content warnings. This is common with WordPress migration and can usually be fixed by updating URLs in your database or using a plugin. * Payment Gateway Errors: If Khalti or eSewa payments fail, double-check your website's API keys and callback URLs in your payment gateway settings and ensure they are compatible with the new server environment.
