Apache committers are granted shell access to a host know as either people.apache.org or minotaur. As you may know, there has been a two year grace period in which we have advertised the upcoming change away from password logins to SSH key only.

Due to a recent significant increase in security issues, the Infrastructure team has taken steps to complete the implementation of key-only logins to protect ASF computing resources. 

If you can't access the host anymore then it is very likely you do not have your key stored in LDAP.  Please check your LDAP data in https://id.apache.org - and add your key(s) if they are not present.  If neccessary, ensure your keys are loaded locally (for linux see http://linux.die.net/man/1/ssh-add  and http://linux.die.net/man/1/ssh-agent)

The host will pick up this change within 5 minutes of you making your change and you should be able to get in again.

As always if you have any issues please open a JIRA issue in the INFRA project and we will help you as soon as we can.
