The Center for Computer-Assisted Legal Instruction (CALI) has informed BLS Library that they have been having issues with the stability of instances in the CALI web cluster that have taken www.cali.org offline for extended periods over the last few days.
If you try the CALI website and it is down or slow please wait an hour or so and try again.
They hope to have this problem rectified soon and are sorry for the inconvenience.
