The previous network glitch was not a DDoS; it was an unreported error in the daemon. Removing the blockchain and resyncing fixes the problem. This needs to be examined, or this could happen again in the future.
Yes,I agree.It is a bug in DSH deamon,has nothing to do with attack.
BTW: Removing the blockchain and resyncing fixs the promble for a short while,hours later,the same problems happened again.
