Is the Hub TKLBAM's central point of failure?

Yes and no. On one hand, much of the streamlined usability of TKLBAM depends on the availability of the Hub. On the other hand, we designed TKLBAM to degrade gracefully if the Hub ever goes down (it shouldn't!).

As we scale the Hub we will gradually add capacity and build in additional layers of fault tolerance.

We have monitoring in place which alerts us immediately if anything unexpected happens.
