What is up with the network right now? We don't have a single running MasterNode (according to biblepay.eu) and also lichtsucher's purepool seems to be down (doesn't count any shares right now). However all my miners are working and show no problem with poolmining!?
The Purepool is processing shares, but I also activated a new cache for the frontend right now. I will add more clear information on the frontend about the caching

But I will ensure that no problem was created by the caching. I now get more http 400 codes in the logs. Might be a problem of the cache, or somebody is spamming the pool with invalid requests.
