This seems to be normal - announcements only succeed once they have reached an HTL of 2 or 3. It would seem that announcements are very sensitive to overload, and become rapidly more so as HTL increases. Thus the combination of an excess of transient nodes hammering the same seednodes, a bug that has been recently fixed, and the momentary overloads (that last for at least a minute) that occur spontaneously thanks to the routingTime-based overload detection, or maybe due to some bias in the way we choose the next hop in an announcement chain (currently we route to a random key), in most cases the node, which handles normal traffic perfectly well, tries five nodes when handling an announcement message and they all return QueryRejected due to overload. I have no idea why, except that maybe the network is hopelessly overloaded but we don't notice it except in announcements. > > > > Question: What causes announcements to fail? > > Lots of things.
