Is ISP redundancy possible with a MPLS VPLS ?

I have two ISP provide MPLS L2 VPLS , Is ISP redundancy possible with a VPLS ?

I've already though about using IP SLA but there's issues when WAN in remote site is down I would have no way of knowing it.

can someone explain how to acheive this ?

I beleive so, but make sure your ISP enable split-horizon under the bridge-domain, so this will not cause a L2 loop.

It is possible but you need to check with your ISP, they either provide you with another circuit terminated at the same PE or another PE.
