13hrs offline and counting

Agreed. I am not understanding the "maintenance" part of it. I miners at a couple of other sites in the USA that are never down more than an hour for planned maintenance.
May 04, 2015, 11:25:41 PM
Less than eight more hours on the projected downtime to go. I expect it to overrun as usual. Please prove me wrong! 
Who would watch a live stream of the work being done if it was available? I know I would, I'm having a hard time figuring why all these problems occur.

Wouldn't you know it; my pool's luck is up now that all 15 of my miners are offline during maintenance...5 blocks in 3 hours...141%. The past 2 days it hovered in the 80% range.

ive got an idea for you guys.. setup a stratum proxy point your miners to that.. then you can change to whatever pool you like when you want to.. if your stratum hangs or you need to reboot it then the miner wil just fail over to the next pool.. Also i know someone from china. its notorious for hit and miss internet.. https://github.com/Stratehm/stratum-proxy

I actually use miningrigrentals, they have an asia-pacific node, and occasionally the connection is great and stable for days, then it's not so great. But I stay way ahead always getting the highest payouts I can get.

Chengdu Data center will do maintenance on 5/5/2015, The maintenance will start from 8:00 and end at 20:00(Beijing time, GMT+8), sorry for the lose of mining time, and we will cover the lose
What's going on ?
Also, When our miners go on and off, this isn't reported in the offline history. I got numerous emails from my pool warning me that the miners was ON and OFF for around 36 hours.
I received an email from Lee stating yesterday that their internet connection from Chengdu was not stable (no surprise). This was corrected late yesterday after about 24-36 hours of pool jumping and reduced hashrates.
I have had a few machines with short term issues today, but all are running fine now.
I sent back my credit notification for April with questions due to the chart having both negative and positive downtime hours. The result was lower credit owed than the monitor site shows.
I added notes about the fact that when the internet connection goes bad, the reduced hashrate and pool hopping does not show as downtime. For me it is at least 50% down time. So I recalculated and added hours owed for credit.
No response yet.
The Neimeng miners being swapped for miners in Chengdu is leading me to have a hard time calculating out the amount to be refunded. If it takes me a page of calculations, I do factor in all the reduced hashrate time, even per miner if I have to. This time for April's return with previously one miner at Chengdu, and the rest at Neimeng makes me think since every hour counted towards the Neimeng miners, I really can't beat that number even with hours not listed in the host website.

I had my first miner that I got, go offline yesterday. Lee sent me a picture of the web interface status page after it was restarted... Take a close look at those temperature numbers. I had another miner, the second one I purchased, go offline today! What happened to the dusting out? Why is it so hot? The questions are piling up.
I believe everyone will have miners going offline due to overheating. This needs to be fixed. If overheating, it must be like a dry desert in the building that's being mined in. I hope they aren't all piled one on top of each other in someone's garage. Yep, that's what I'm picturing now.

Guys the symptoms you are describing is exactly what the miner will do once it reaches 80c all Lee could do is shut off that trigger but for them to be running at that temp when its not that hot in china YET.. wish you all the best of luck. My c1 antminer once they leak all the fluids out they will show connected to the proxy and show them mining. But here is the kicker.. Its only using just a little bit of power.. So lee is getting the maintenance fee regardlesss of miner not using all that power.. if it keeps over heating it will limp along at about 10 - 20 % capacity.. So his miner monitor is useless in this case..

Agreed - downtime like this is not being recorded. I took a snapshot of all my miners with them. In addition to running slow, they are also constantly switching pools. So the ones that are working are bouncing off all three pools every 20 minutes to so. My inbox is overflowing with pool alerts.
If I add the hashrate for these miners on all three pools it's 47% of expected. Started around fight time last night.
I can confirm bouncing, but my overall hash rate is much lower than 47%, here are my pools:If I add the hashrate for these miners on all three pools it's 47% of expected. Started around fight time last night.
Also monitoring system is not reliable starting from 1-st of May. It's missing zero hash-rate drops longer than 2 hours.

looks very unhealthy. is one dc performing better than the other or is it more random?

I have tried both the AntPool and f2Pool and I get basically the same averages; 0.0122 for AntPool and 0.0115 for f2Pool (per miner per day). I tend to stick with the AntPool but I switched for a while during the attacks. All my miners are now in Chengdu.

thanks for the trust, now both neimeng data center and chengdu is stable like before, we will send compensation list as soon as possible
good thing is that both the difficulty and btc price keep the same as before, so we have got a lucky 14 days again

The problem for me are the following:
- The miners are getting too hot. You have not told us your plan to rectify this.
- We need lower host fees, but your current cost for new miners is holding people back. I know these machines still ready to sell are being mined, so I don't understand this high cost.
- We need more data in the host website. Whatever you are currently using to monitor the machines needs to do more, like show current blocks accepted for the pools, etc, and the temperature of the blades.
- The miners connectivity is generally poor. They jump pools too much and can't keep solid connections. Any plans to make this better?
- It would be wonderful to have an ability to ping and traceroute from the host login. That way we can pick better pools or nodes to use.
Thank you, and good luck with getting back on here more often.
-------
Additionally, I see all my miners moved to Chengdu, and have different IPs. Did I keep the same machines or what happened there?
i wouldn't mind more stats on the monitoring page.
i don't seem to suffer from pool hoping at all. i point mine to either f2pool or antpool pools. most of my miners are in the neiming dc.
I run my 12 all on f2pool and they are rock solid. 4 in one location 8 at the other. I've run S5s at home averaging around 74c on one and it ran solid for 5 months until I sold it. I'm not worried about temps so much. You're list is a lot of bitching. Sure things could be cheaper but they are already a hell of a lot cheaper than running them in my basement.
F2pool does not payout highest rates available most of the time, but it is an excellent last fallback pool. When I have to report a different miner down almost daily, I worry. I manage to get a respite occasionally, but here's the days of the last eight reports: 19th, 21st, 24th, 24th(2nd miner later), 26th, 26th(2nd miner later), 27th, and today.
i'm interested in comparing pool performance and rewards if people are willing to share. i'll start:
1. f2pool has been very stable for me that last 6 weeks and averages around 0.0114 btc per miner per day.
2. prior to that antpool was also a good stable pool, apart from the ddos attack on it, and was averaging a bit higher around 0.0123 btc per miner per day.
if there are better performing ones that we can get a reliable connection from i would definitely like to try it out. all my miners are located in the neiming dc.

I have all of my miners in the Chengdu data center now. Only 6 out of my 15 are showing any hashing at all and they are just barely registering in the pool...the other 9 are just missing. I've seen nothing but low GH/S for the past 9 hours. The real kicker is I only have 2 downtime hours to show for it so far; when the hashrates get super low they are not registering as offline even though they drop out of the pools. Several of my miners are showing all three pools as being dead even though they are not offline. They are not producing hashrate anywhere but they are not offline in the Miner Monitor.

It's even worse, I'm at 2900.9 Ghash/s and falling right now instead of 14000+
May 03, 2015, 02:50:27 PM
my 3 s5`s have been running today for about 8 hours at a vastly reduced hashrate. one showing offline completely and the other two runing at 45 to 600 ghs each. easy2mine.com is down also.
Anyone else at Chengdu having difficulties?
Pcfli- can you look into?
