- The TTL (Time to Live) value configured in your DNS records — When configuring a DNS record in your domain's DNS zone, you can select the TTL value, which defaults to 3.600 seconds in Clouding.io. The TTL is the amount of time the DNS record will spend in the DNS servers' cache. For example, if you set a DNS record's TTL to one hour, the servers will store this record's information locally for one hour before sending the updated information from their authoritative name servers. Shorter TTL settings can increase propagation speed. However, shorter TTL settings will also increase the number of queries to authoritative name servers, and this would slow down loading on your name server, causing it to run more slowly.
- Your ISP (Internet Service Provider) — Your ISP's DNS record cache stores data locally instead of retrieving new data from the DNS server to speed up web browsing and reduce traffic, which slows down propagation. Some Internet providers ignore TTL settings and only update their cached records every two or three days.
- Your domain registrar — If you change your domain's name servers, we forward your change request to our registrar within minutes, and they publish the NS (name server) records to their root zone. Most registrars update their zones promptly. However, not all registrars perform updates as quickly. Registrars often protect their root name servers from excessive use by setting a high TTL of up to 48 hours or more for NS records. In addition, although recursive name servers should not cache root NS records, some Internet providers cache the information anyway, which can result in an extension of propagation time.
Note
Many of the updates you can make in the “Administrador de dominios” in your control panel will affect the DNS records in the domain name's zone file. For example, if you configure name servers, configure IP addresses, create a new subdomain, or modify the subscription the domain is associated with, you are updating your domain's DNS zone.
