BREAKING: Ethereum client geth has an error which is exploited right before ethereum devcon 2 !!
There seems to be an issue with the geth client for ethereum nodes at the moment.
Some bad guys want to harm ethereum. They exploited a bug in geth client which leads to fail all geth client based nodes.
The transaction payload that lead nodes to stop working can be found here:
What does the payload means in ASCII? 'Fahrt nach Hause' - that means Go home in english and possibly refers to Devcon 2 participators which starts September 19th 2016 (Monday).
You can see the issue reported on github here:
As far as we know only geth and not parity is affected. Thanks to different client the ethereum network is still running.
http://ethermine.org (Ethermine mining pool) has switched to parity client, others will follow.
Gustav Simonsson from the Ethereum foundation wrote on reddit that the devs are working on the issue and a post will be made at https://blog.ethereum.org the next hours.

At the moment the network seems to be safe, hashrate is growing while people are updating to parity.
See the current stats @ https://etherchain.org or https://ethstats.net
Price fell for a moment and is now relatively stable a little over 0.02 BTC. (Price ticker here https://cryptowat.ch/poloniex/ethbtc/1h)
Interesting part is: ETC is even more at risk. Anyone could run the same contract and transaction on the ETC chain. Bad part is that ETC has nearly 100% geth clients which would lead to network halt. If someone has bad intentions, that person could exploit the bug and run a 51% attack on ETC (it has way less hashrate). The trading on ETC (Kraken) is totally irrational though: https://cryptowat.ch/kraken/etcusd/1h
As we observe ETH and ETC have a strong negative correlation in their prices. However, ETC is even more at risk and price should fall even more. Shorting ETC would be a good idea now. Whatever.

Payload: 'Weltreise' ('world journey' in english)
