Topic: Huge ~40% Drop in Network Hashing Power (5/27/2011) - page 3. (Read 9235 times)
deepbit.net is down! that is why.
probably some miner finally managed to melt his substation/transformer and he is alone in the dark 
Indeed it is good for those of us in it for the long haul! I was hoping this would happen
This is... GREAT news for those of us still mining! Hopefully this is a sign of difficulty beginning to level off... I doubt it will stay that low, but I can hope, can't I? 
Is this a joke? This happens everytime the difficulty increases.... the accuracy of the hash rate calculation is not correct because of the 24hr sample rate. I would assume someone with a few hundred posts on the forum would know better....
Please read the thread.
Edit: This is based on the graphs from http://bitcoin.sipa.be/ which do not have the same calculation flaw right after a difficulty change that BitcoinCharts does.
The sipa charts are not based on BitcoinChart's network hashrate calculations which are flawed around the time after a difficulty change.

The sipa graph is the graph that I posted in the OP. It shows a 40% intraday swing. If you look at some of the other graphs on the sipa site, you will see that it those graphs do not have the same difficulty change miscalculation as bitcoincharts.
The total network hashing power started 5/27/2011 UTC at ~5THash/s and swung to close the day at just over ~3THash/s. With a low around ~2.9THash/s.
That is a nearly 40% drop, day over day, in the first full day after the latest 78% difficulty increase.

Actually the green lone is an 8 hour moving average.

YAY!!!!!!!

So? dit that sipa charts show any drop in network hashrate ? Or they just to much flawed around difficulty raises ?

Bitcoinchart crude assumption on difficulty, total hashrate, [...]
No, but also remember that hashing power is calculated based on the current difficulty and the last few blocks. So when there is a dramatic increase in difficulty, this throws off the calculation, which can explain why the hash power shot up above 5Thash and then back down to 3.4Thash. btcguild was doing almost 300Ghash, which would put the network at 3.1Thash, which appears to be where it dropped to.

btcguild was down, it seems to be back up now.
BTCGuild alone doesn't account for a ~2THash swing, though.

Bitcoinchart crude assumption on total hashrate, and mainly - psychological factor of that assumptions on fresh miners did that.
Many is quit from mining.
