No action in starter

I have 1600ml of a starter mixed with 5 oz of DME, boiled and cooled, piched White Labs WLP060 and no action yet. I got this from a small LHBS and never have gotten it from there before. I think it might be shot.

Times and dates please?

It took about 28 hours to start bubbling, not sure what happened, but it put my brew day a day behind.

Sounds like the yeast was little old. I’ve had starters take a day or so to start up. Glad to hear it’s doing it’s thing.
