What does a 429 Too Many Requests error mean?

A 429 Too Many Requests error is the website asking you to slow down. It is a deliberate limit, not a breakage. Servers use these limits, called rate limits, to stay fast for everyone and to stop abuse.

Why you might see it

• You refreshed or clicked very quickly. Repeated reloads can reach the limit within seconds.
• You share a network. Offices, schools, mobile networks and VPNs put many people behind one address, so their combined traffic can hit the limit even when you have done little.
• A browser extension or app is making extra requests in the background.
• An automated tool or script is calling the site too often.
• The site is under heavy load and has tightened its limits temporarily.

What to do

1. Wait a few minutes without reloading. Some sites say how long in a Retry-After message.
2. Close extra tabs and pause any extensions that interact with the site.
3. Switch from a VPN or shared network to your own connection, or the other way round.
4. Try again later. Limits usually reset within minutes or an hour.

If you run the site or write the tool

Slow your requests down, spread them out, and respect the Retry-After header. If real visitors are being limited, raise the limit or give known users a higher one. Rate limits that are too tight look like an outage to visitors.

How we treat 429 answers

A 429 from our checking server does not mean a site is down. It means the site declined to answer us at that moment, so we mark the result as inconclusive rather than reporting an outage.
