The MSE 8.130.0 and CMX 10.2.1 sandboxes are currently being moved to another server. We will have them back ASAP.
We apologise for any inconvenience this has caused and will keep this community updated.
CMX 10.2.1 sandbox msesandbox.cisco.com:8081 is now available. We're very sorry for the delay but ran into some snags moving the machine images to another VMware server. Thanks for your patience in this matter.
We are still working on getting MSE 8 back online.
