A weekly maintenance window is scheduled on the testbed. During this two hour period:

• You may not be able to access experimental nodes
• Swap ins, swap outs, and modifies may not succeed
• Other intermittent issues may occur

We do our best to ensure that experiments which are swapped in will be in the same state before and after the downtime.

• Nodes will not be removed from experiments
• Data on experimental nodes will be accesible after the downtime

If you have any questions, please contact Testbed Operations.
