Testnet3 is being flooded by 1 or a handful of individuals, probably not even for malicious purposes but to stress test the network. somebody with a few thousand coins can tie up testnet for a long time. its been happening for about a month, a lot of testnet services shut down, primarily the faucets.

looks like it will end eventually, or a new testnet will be released. in the mean time, use high fees and WAIT. ive been having a hell of a time finding coins and being able to get transactions to be accepted in a block, but not much anybody can do aside from using super high tx fees so you can get accepted in a block .
