We have previously had to modify the ICP API management policy. We are about to implement additional changes that will impose further restrictions on the number of calls able to be issued to the API. These changes will take effect at the close of business today.
The steady increase in large aggregate call volumes coming through the ICP connection data API have been continuing to adversely impact the underlying registry infrastructure. Further complicating matters, the registry manager has had to implement more restrictive firewall policies to guard against malicious activity. To preserve the integrity of their system and its responsiveness, the registry manager has further reduced the number of concurrent calls they will manage.
We're making adjustments to our API management policy on the ICP API in line with this. These changes are designed to smooth out the load spikes our users collectively generate on the registry system.
The new management policy is below. Once user load on the registry systems has stabilised, we may revise this policy.
A management policy is set on this API restricting users to 250 calls per minute for ‘search’ and ‘get by id’ calls and the multiple ICPs ‘get by id list’ call will no longer be available.
