Your IP address may be blocked for one of these reasons:
Amount of Requests
We block IP addresses that seem to generate an excessive/abusive amount of requests to our servers – much more than can usually occur from legitimate use of the Toolbar or from visiting our site.
This blocking is automated, and sometimes innocent IP addresses are blocked. We can review and manually unblock affected addresses.
If you have an address that has many Alexa toolbar users, or is sent through a proxy, the actions of another user may trigger the block. Likewise, the aggregate usage may look like abusive behavior to our system.
We regret any inconvenience this measure to protect our servers from abusive activity may cause you. We strive to protect our service and make it available to the greatest number of users.
If you experience this kind of trouble, please contact us with your IP address. If you do not know your IP address, you can use www.whatismyip.com to find it. We’ll be happy to unblock it if possible.
Note: If you need programmatic access to the data on alexa.com, please use our Data APIs.
Due to export controls and economic sanctions laws and regulations, we are unable to provide you with access to Alexa.com from your current location.
