Propagation

Why DNS changes are not immediate

DNS propagation is the time it takes for a change to the records to spread across the whole network, because many servers keep a copy of the old information for a while.

The actual time depends on the records' TTL value and on the cache of the various providers, so it cannot be predicted exactly. That is why it is best to plan changes, especially for the websites of companies between Como, Milan and Lugano that cannot afford interruptions.

  • Record TTL: how long servers keep the copy
  • Cache of the internet provider and of the device
  • Type of change: website, email or nameservers
  • Planning done in advance by the team

Websites we follow from domain to server

Need to change your DNS without downtime?

From our office in Cantù, in the province of Como, we plan every step with you.

Services of interest

Nameservers are the servers that hold the domain's DNS zone and say where website and email are located. Changing them moves the management of all records, so it is best to copy the current zone first. We take care of it from Cantù for companies in Como and Brianza.

To connect a domain to a website, you set a record in the DNS that points to the website's server, then configure the server to recognise that domain and activate the security certificate. From Cantù, in the province of Como, we follow the whole step for companies in Milan and Brianza.

In Cantù you can entrust the DNS configuration to NewVisibility, a web agency with an in-house team in the province of Como, directly managed servers and CSSDA award-winning websites. We look after domains, email and servers together, for companies in Cantù, Como, Brianza and Milan.

The server has a significant effect on website response time, together with code, content weight and configuration. That is why in Cantù, in the province of Como, we optimise hosting and website together, also for companies in Brianza, Milan and Lugano with content-rich projects.

The registrar registers the domain and handles its renewals and ownership details, while the maintainer takes care of technical and administrative management, such as DNS and support. Sometimes they are the same. NewVisibility, in Cantù in the province of Como, clarifies the roles for companies in Como, Brianza and Milan.
