How often do seed addresses change?

For newer seed addresses, your seedlist may change on a monthly basis as 250ok releases new ISPs into its coverage.

For existing seed addresses, we proactively rotate new and old addresses throughout the month as we identify issues through real-time monitoring.

It’s important to log into 250ok regularly and check the status of your seedlist. Whenever we add new addresses or require an update on your end, you’ll be alerted through the interface on the “Get Seedlist” page.
