Is the website down, or just you?
503 Service Unavailable means the website's server is working but can't handle your request right now. The most common reasons are planned maintenance and too much traffic, for example during a big launch, sale or outage elsewhere.
The "temporarily" is important: a 503 is meant to be short-lived, and servers sometimes include a Retry-After header saying when to come back.
What you can do
- Wait a few minutes, then reload. Reloading constantly can make an overloaded site slower for everyone.
- Check if it's down for everyone with our website checker or the service's page in our status list.
- Look for a maintenance notice on the company's social media or official status page.
- If it's only you, restart your router and turn off your VPN. Some sites return 503 to traffic they consider suspicious.
If you run the website
- Check whether the server is overloaded: CPU, memory, database connections and worker or process limits.
- Make sure maintenance mode was switched off after an update (for WordPress, delete a leftover
.maintenancefile). - Check that your application process is running and that a crashed service didn't leave the load balancer with no healthy servers.
- Send a
Retry-Afterheader during planned maintenance so search engines know to come back.
Questions
Does a 503 error mean the site is down?
It means the site can't serve pages right now, usually because of maintenance or heavy traffic. It's typically temporary.
Will a 503 hurt a website's Google ranking?
Not if it's brief. Google treats 503 as temporary and comes back later. A 503 that lasts days can lead to pages being dropped.
