What is the difference between "https://community.cloud.automationanywhere.digital/" and "https://community2.cloud-2.automationanywhere.digital/" both the community edition links?

The first URL is "https://community.cloud.automationanywhere.digital/" developers got this access who registered when a2019 and a360 was introduced. But later, to reduce the load they are giving the second URL "https://community2.cloud-2.automationanywhere.digital/" for the new developers who are registering a360 community access.
