Otherwise, follow the steps below.
Step 1: Add Four A Records for yourdomain.com
Bibliopolis uses Fastly, a content delivery network (CDN), to host images and improve site performance. To connect your domain to Fastly, you'll need to add (or replace) your existing A record with these four:
Host TTL Type Value
yourdomain.com | 300 | A | 151.101.1.91 |
yourdomain.com | 300 | A | 151.101.65.91 |
yourdomain.com | 300 | A | 151.101.129.91 |
yourdomain.com | 300 | A | 151.101.193.91 |
Having four A records is normal — this is how Fastly ensures reliability and performance across its global network.
Step 2: Update the CNAME Record for www.yourdomain.com
i. Find the record forwww.yourdomain.comand note whether it's an A record or a CNAME record.ii. Remove any existing A record forwww.yourdomain.comif one exists.iii. Create or update the CNAME record forwww.yourdomain.comand point it to:
n.sni.global.fastly.net
This routes all www traffic through Fastly for improved speed and reliability.
Before You Make Changes
1. Set TTL to its lowest value for all records — ideally 300 seconds (5 minutes). This helps the changes propagate across the internet as quickly as possible.
2. Notify us the moment changes are made. There may be a brief period of downtime during the transition, and our team will be standing by to resolve any issues right away. Email us at support@bibliopolis.com.
