I can't get my RPi to work very well with the pool running Minepeon

- Lots of downtime in the past 5 days
- Currently ghash.io and cex.io offline (cloudflare) again for the 2nd or 3rd time
- Approx 3-4 times my miners have hopped to their secondary pool
- Multiple times I think their mining server goes offline, several stale shares in a row (5 stale blocks out of the past 100)
- Whenever I see a very long blocktime (5 hours at 800GH/s 880TH/s is a very long time) I wonder if their backend is down.  The consecutive stale blocks were a 3hr stale, a 1 hour stale, followed by another 3 hour block
- Large swings in hashrate, from 820GH - 600GH - 820GH

I've been playing with cex.io a bit, mostly because of how easy it is to turn a quick profit in speculation/manipulation.  I've noticed these, and I'm going to *guess* they are actually related.

1) Downtime is *probably* due to attacks [my guess is they're just overloading the webserver, not actually a bandwidth saturation ddos]
2) See #1

3) Failing over to secondary pool is probably network related (NL servers aren't always the most stable in my experience).  Could also be attack based, or even just growing pains since they never really operated a public pool before.
4) The mining server offline and several stales would be related to #3.
5) Also may be related to #3, but also: VARIANCE.  Even at 800 TH/s, 3 hour blocks aren't that uncommon.
6) My guess:  GHash.io's internal speed is in the ~600 TH/s range.  The remaining ~200 may be other miners, or personal miners of the people involved with ghash.io (BTC Guild has a miner that comes & goes at over 100 TH/s, might be using ghash.io as primary since they don't show up on any major public pool when they're not on Guild).  When they drop from 820 to 600, that may be their public pool server failing, either actually crashing, or simply not communicating with their backend properly.


All of the above are guesses, but they're educated guesses from someone who has been running a pool with multiple servers in multiple regions for 2 and a half years.  A lot of the problems you mentioned are extremely likely to stem from the same cause.

There was a significant drop in pool hash rate today



And since 29th Oct, my miners have hopped to their secondary pool with 3 dips in hash rate



On their forum they report being under DDOS attack earlier this month.

According to the email I just got, a server popped a DIMM rack in their data centre.  Downtime again later to replace the broken bit.

The sky is not falling. 

They are not DDoS'ing BTCGuild.

They are not ping flooding the NSA.

It has been very stable (like btcguild) up to mid of this past week.  Still, my workers (both physical and virtual) have recovered.
I see 4 dips in the last 3 days.

I had 2 more dips shortly after your post and ghash.io is down again ! Going to the cloud flare page, with my secondary pool notification email

On a lighter note, I went through my daily average hashrate, and multiples by the ideal earnings (plus any PPS from my secondary pool)

The earnings for the past 11-12 days have been within 98.5% of ideal income, despite the disruptions and the presumed network problems with consecutive stales, etc

seems like my hashes aren't working right now , as per GHASH ( cex.io based ones atleast )

OregonMines will have additional large hosting space for customers by August 1st. Current customers have access now.

I still cannot reach the worker or finance pages, the homepage is a cloud flare cached copy for me.

They did solve a block 9 mins ago at 702TH so 250TH missing.

Must have been some blip. My hosted miners went down to 31MH/s, then 2 hours later came back at 26GH.  I only have 10GH.

I pointed my 5 MHS at doge.ghash.io:3333 last night and been mining for 12 hrs now. The real stats are fine and hashrate is what it is, but strange thing is I did not earn a SINGLE DOGE yet. My balance shows 0.0000000 DOGE and that's for 12hrs of mining. I don't know what's the catch with them but I am going back to my tested pools.

My advice for ghash.io is stay away!

I mine BTC at ghash and it works very well. Rewards are paid on block completion, DOGE blocks can take hours, block 202076 ran 12 hours perhaps your timing was just unfortunate during that block.

It is worth mining at this site, the overall experience is very good, but unfortunately my ISP blocked port 3333, what makes me very depressed.

Ghash is definitely worth mining at. Is it your ISP or your own router / firewall that has blocked ports? If you can identify that then yuoucan fix it.
