Progress is being made to mitigate the denial of service attack.

One component of the denial of service attack is to create hundreds of thousands of new accounts, causing stress on the infrastructure. For that reason, please note that new user signups have been temporarily disabled to help defend against the attackers and improve platform service for existing customers.
