Is Pingdom Effectively Dead?

Is Pingdom effectively dead/abandoned/stale/whatever? Seems slow and buggy and support is unresponsive.

I guess I already know the answer. So any recommendations for a similar product that will monitor endpoints as well as do simple "go to that URL, click the link, check for text" kind of scenarios? Doesn't have to be free. In fact, I would prefer to pay for it.

Thx!
