Why do websites go down, and what should I do when mine does?

What does it mean when a website is down?

A website is down when visitors cannot access it as expected.

But not every website problem is a complete outage.

Sometimes the homepage loads while other pages fail.

Sometimes the website works but the contact form doesn't.

Sometimes visitors see an error message.

A browser warning that the connection isn't secure, for example, can mean an expired SSL certificate.

And sometimes the website loads only intermittently.

Those situations may have different causes.

We'd begin by describing the actual problem.

What happens when someone visits?

Is there an error message?

Does the problem occur on different devices?

Does it affect the entire website?

That information can help narrow the investigation.

Don't assume every failure is caused by the hosting provider.

A domain name and web hosting are separate services, and either one can fail on its own.

Can hosting problems cause an outage?

Yes.

Hosting infrastructure makes the website available online.

If the underlying service experiences a failure, visitors may be unable to reach the site.

The problem might involve servers, networking, storage or other infrastructure.

Managed hosting providers may publish incident information through status pages or support channels.

We'd check those sources when an outage occurs.

But don't assume that a provider status page will identify every issue affecting your specific website.

An application configuration problem may affect your site without causing a broader service incident.

The distinction matters.

You need to know whether to wait for a provider's recovery or investigate your own website.

What happens when a domain expires?

A domain registration must be maintained according to the applicable registration and renewal terms. ICANN, the group that oversees domain names, says a registration period is typically between one and ten years, and that registrars must send two renewal reminders before a domain expires.

If the registration expires and isn't restored, the website address may stop functioning as expected.

That can also affect services associated with the domain.

Business email may be disrupted.

Customers may struggle to reach the website.

And eventually, control of the domain may be lost, depending on the registration process. ICANN says that after an expired domain is deleted, there is a 30 day redemption period when it can still be restored, and after that it is released for anyone to register.

We'd keep domain account access within the business.

Maintain accurate recovery information.

And monitor renewal notices.

Don't rely entirely on a contractor to remember when your domain needs renewal.

The domain is a critical business asset.

What is a DNS problem?

DNS stands for Domain Name System.

It helps direct requests for a domain to the appropriate services.

If DNS settings are incorrect, visitors may not reach the website even when the hosting infrastructure is functioning.

This can happen during migrations.

Someone may change a record incorrectly.

A domain may point to an old service.

Or configuration changes may not behave as expected.

We'd be especially careful when changing hosting providers.

Record the existing settings before making changes.

Understand which records support the website and which support email.

And test the new configuration.

Randomly changing DNS settings can make troubleshooting more difficult.

It can also disrupt unrelated services.

Can a software update break a website?

Yes.

Some websites depend on content management systems, plugins, themes or custom application code.

Changes can introduce compatibility problems or errors.

A feature that worked before an update may stop functioning afterward.

That's why testing matters.

We'd avoid applying major changes directly to a critical production website without an appropriate plan.

For more complex systems, a separate testing environment may be useful.

Backups can also help with recovery.

But a backup isn't valuable unless it can be restored successfully.

Know what the backup contains.

And understand how the recovery process works.

Can too much traffic take a website offline?

It can.

A sudden increase in requests may exceed the capacity of a website or its supporting services.

But the effect depends on the infrastructure and how the application is designed.

Some hosting systems can handle significant traffic changes.

Others may have more limited resources.

We'd avoid assuming that every traffic spike requires an expensive server upgrade.

First identify the bottleneck.

Maybe the application performs inefficient database operations.

Maybe large files consume unnecessary resources.

Or maybe the traffic isn't legitimate.

The right solution depends on the cause.

Adding more hosting capacity won't necessarily fix inefficient code or abusive traffic.

What should you do during an outage?

Start by confirming the problem.

Try the website from another device or connection.

Check whether other people experience the same issue.

Look for error messages.

Review relevant hosting and domain status information.

Then contact the person or provider responsible for the affected system.

We'd avoid making several unrelated configuration changes at once.

That can make the original problem harder to identify.

If the business depends on the website for inquiries or sales, establish an alternative contact method when practical.

Communicate clearly with customers if the disruption affects important services.

And document what happened so the business can reduce the chance of recurrence.

How can you prevent future outages?

You can't guarantee that a website will never experience downtime.

But you can reduce avoidable risks with regular website maintenance.

Keep domain registrations current.

Maintain appropriate backups.

Monitor important services.

Test updates.

Protect administrative accounts.

And document who controls the hosting, domain and integrations.

We'd also identify critical customer functions.

If the website supports bookings or payments, those workflows deserve monitoring.

A website may technically be online while an essential service is broken.

At Veshtera, our optional Website Care and Hosting Plan costs $199 to $499 a month. It renews monthly and can be canceled with 30 days notice. We don't promise that a website will never go down.
