The one time I relied on the pool I lost sync a year later when all three servers the configuration picked withdrew time services and the still-running ntp client didn't return to the names to find new ones. Wonderful if that's fixed now but the pool folks argued just as strongly for using it back then.

Also, telling the security auditor that you have no idea who supplies your time source is pretty much a non-starter. You can convince them of a lot of things but you can't convince them it's OK to have no idea where critical services come from.

That's what's wrong with the pool.
