Bug in Blockchain.info.
I checked 'stats' page on blockchain.info at that time, and there was number 86 for 'blocks mined last 24 hours'.
I then checked mined blocks myself, and counted 156.

I though so!

it was not possible to lost 50% just like that!
Sometimes some bugs over all times charts are making ticks that are not easy to understand.

Time is on our side, yes it is!

Good I'm glad to learn it was a bug as I couldn't for the life of me understand why something like that would happen. I've not been aware of this so thanks very much for bringing it to my attention.

If the price keeps falling perhaps we'll see a drop but it's not going to be cut in half just like that

If the price keeps falling and stays down: we may see a flattening out of the hash rate in 6 to 12 months, possibly a dip, but doubtful; it would most likely mean the end of exponential increase in difficulty ---- stretched out in time, due to miners having committed capital for mining operations beginning months in the future.

I do not necessarily expect much of the network hash capacity to just up and quit any currently mining operations, as they already spent the investment on the expensive gear, and there are very likely many miners with pre-orders of mining equipment as well, some which have committed and can't just cancel or back out.

Would most likely serve to raise the bar on minimum hashes per unit of investment expense,
for new mining operations.

which also mean higher price support.

Update: Hash rate returned to normal now, it seem there was an error at Blockchain.info

Stunning graph even without the bad data.
FYI: The big rise is starting ~Oct 2013.

Never get your sources of information from one place, otherwise you may end up with the wrong information.

Because of price drop. At this current price mining is not profitable.

Said is reasonable, I will stop mining BTC.

well this is interesting, maybe some China miners are switching off their rigs?

or just some bug ...

It has been classified as a bug already...

I only wish the hash rate dropped in half. Mining is so much slower than it was not too long ago..

I've seen this exact thing before with the market cap graph. It's a glitch from blockchain.info...We will definitely see a decrease in hashrate due to this price drop but not that severe.

Mining rate is still holding strong so far. It's up almost 20% since last adjustment.

There isn't any drop in hashrate...stop panicking people!

blockchain.info chart 30 minutes ago:

it seems there was an error, everything back to normal now.

"it seems there was an error, everything back to normal now." You mean blockchain.info error so it just seemed like drop.

I noticed that the ZeroBlock app is reporting a block time of 17 minutes, but being on my phone I haven't been able to verify how they've come to this conclusion.

It seems reasonable that they could be estimate block time based on network hash rate as reporting by blockchain. In which case, this is explained by DeathAndTaxes. I'm just not sure where they're (ZeroBlock) is pulling their info from.

ZeroBlock is owned by Blockchain.info, so it would make sense that they pull their data from there.

BC.i is just broken, yet again.

Yep. People are putting way too much scrutiny on a very new piece of software that is in development as we speak.

Most bitcoin-related applications are still 0.X state.

I believe it was forked multiple times and its pretty much game over now. Also dont see how this relates to the BTC hash.

never mind, i were thinking that BTC lost hash rate while AUR received enormous hash rate. But apparently they aren't related.

Aurora is a scrypt coin.....has absolutely nothing to do with bitcoin hash rate.

Is this related to recent incident of Auroracoin ?

What "incident of Auroracoin"?

And how does it relate to BTC hash?

I find it funny that blockchain.info has had numerous errors, glitches, and other problems over the last couple weeks and people treat it like the word of god on stone tablets.

Lets see:
blockchain.info says hashrate was instantly (as in a vertical downward line) cut in half
nobody else is reporting that
block times haven't suddenly doubled to 20 minutes on average

what is the likely reason for that?
