Completely off the grid: https://www.whatsmydns.net/#A/viabtc.comNot doing great but slowly improving: https://www.whatsmydns.net/#A/poolin.comStill a bit shaky: https://www.whatsmydns.net/#A/f2pool.comNot sure if a network issue in the china firewall or what, but it would be interesting to see the failover data stats. One big pool going down like that could cascade to other pools getting knocked out when all the miners fail over to their secondary pools* Unless they are using bitfury software, as that only allows one pool Probably by the time you read this it will all be fixed, but its been going on for a while now, not sure how much its affecting mining or just access to the web sites.

To most folks, it's probably just the website, out of nearly 200 gears I got running on Viabtc only 2 switched to the secondary pool because they were rebooted by awesomeminer for having "sick asics", the rest are unaffected and 0 seconds time on the backup pools. The miners that switched to the secondary pools now showing Viabtc "dead", it will probably go away if I reboot them but I want to see what happens, so my guess is that if the miner wasn't rebooted during these DNS issues -- no issues, someone who runs a pool like Kano probably knows what could have been the problem, why are the previously connected miners running fine, and the ones that are negotiating for a new connection aren't. Anyway, one should always be prepared for such a scenario, the back pool needs to be in a different geographical location.

Discussing this in the KanoPool Discord room: yeah that's correct but I get different answers every 2nd try (to 8.8.8. oh it's just stopped doing it 🙂 only giving correct answers now netghost — Today at 6:45 PM If I look it up I get 75.126.215.88 from the trustzone dns Kano — Today at 6:46 PM you'll get random different answers - not just that one well don't trust them then 😄 Yeah it's definitely something china is doing internally. I just did a ns lookup for kano.is from a vm inside china to one of my dns servers (outside china) and got a completely wrong answer - a single incorrect ip. But doing it from outside china gets the correct answer (2 ips) The actual reply was also completely wrong it said the TTL was 192s which is wrong, a *.is must be at least 1day and kano.is is that 86400 So I guess china's GFW is doing some DNS fuckery to screw with it's residents Hmm - maybe it's only mining? I tend to agree with Kano's last statement about the GFW tho doesn't explain why a lot of other DNS sites around the globe were foobarred for a bit.

My rigs kept mining, everything looked good, until I rebooted my wireless, then every one 'could not resolve host name" Wondering if yours continue to mine, and if they really are mining?

Do you mean you rebooted your router? Well if you did so then it explains why they can not connect anymore as explained in my first post. Yup except for the 2 gears that rebooted the rest kept mining with no issues, in fact the app worked for a while a few mins back and the hashrate was showing pretty normal.

At least I remember it happening.
I left all gear mining ⛏ on viabtc.
The gpus The L3+ The s9 The s15 The s17 The s17+ The t15 The t17 The t17e The t17+ The avalons The whatsminers

A miner wont do a DNS lookup to change an active connection, since stratum is a permanent connection. When the connection is lost or the miner is restarted or rebooted, it may then do a DNS lookup that could be mangled by the problem.

Can't speak for the others but viabtc either broke something or is a fight with their hosting provider. Doing a whois lookup at the global registry you get: Domain Name: VIABTC.COM Registry Domain ID: 1989117527_DOMAIN_COM-VRSN Registrar WHOIS Server: grs-whois.hichina.com Registrar URL: http://www.net.cn Updated Date: 2021-11-25T12:15:46Z Creation Date: 2015-12-23T06:12:17Z Registry Expiry Date: 2024-12-23T06:12:17Z Registrar: Alibaba Cloud Computing (Beijing) Co., Ltd.

This status code tells your domain's registry to not activate your domain in the DNS and as a consequence, it will not resolve. It is an uncommon status that is usually enacted during legal disputes, non-payment, or when your domain is subject to deletion.
Often, this status indicates an issue with your domain that needs resolution. If so, you should contact your registrar to resolve the issue. If your domain does not have any issues, but you need it to resolve, you must first contact your registrar and request that they remove this status code. So it's never even making out. Although the Chinese government may have something to do with it, they are not blocking it at the edge. It IP address resolution does not even exist to make it there. Yes I know that does not help, but it's a bit more info. -Dave

Looks like it might be related to Alibaba Cloud. From CityAMIt seems the major pools of viaBTC, Poolin, F2Pool, Binance and BTCcom suddenly experienced connection interruptions. The only thing they all had in common was their DNS was provided by Alibaba Cloud, a Chinese owned operation. All had stopped resolving. Or its China Telecom trying to block domestic miners reaching chinese pools, but ended up fubar'ing it and blocking the world. From: TheBlockMining pools blocked According to a recent document made by China Telecom and seen by The Block, the top Chinese internet service provider has come up with a detailed solution to detect domestic miner IPs that have communicated with mining pools' URLs.
Based on its ongoing detection, it can either cut off the internet service to specific IPs or manually blacklist the URLs that mining pools use to connect with individual equipment.
As of writing, the domains of almost all the 10 biggest mining pools by real-time hash rate for both Bitcoin and Ethereum are not accessible from IPs inside China, based on The Block's verification.
Among them, F2Pool, ViaBTC, BinancePool and BTC.com have seen sharp real-time hash rate declines by around 10% for either Bitcoin or Ethereum over the past 24 hours.

biffa’s post now shows btc and other pow coins can be attacked with some success via large government interference.
not sure how this unfolds but on some level I really do not like it.

Not really, what it does show is the resilience of POW coins, because you can just easily mine to a different pool and everything just keeps going. It shows that you can take out the worlds biggest mining pools and the network still works exactly as intended. The only risk is the risk of losing the coin that you have accumulated on the pool if it goes byebye. But its not a risk to the network itself and no more of a risk than if the pool dissapeared because the operator was inept or crooked.

Got this from ViaBtc a few hours ago: Dear ViaBTC users, Recently, due to the impact of DNS pollution, some of the users in certain regions experienced abnormal resolution of the ViaBTC domain name ( www.viabtc.com) and were unable to access the website properly. After emergency maintenance, ViaBTC has activated a new domain name ( www.viabtc.net). If you have ever encountered the above situation, please use the new domain name to visit the website. DNS pollution as in spoofing? Poolin and F2pool were reachable at noon (GMT), viabtc.com was off, can't test .net for a while to see if it works.

I have several rigs pointed at all three of VIABTC stratum servers Most still connected & hashing
1 rig in particular got disconnected and won't reconnect. Tried changing to a different pool on that rig and it connects as normal. Changed back to VIABTC several times and still won't connect

It is, they put an announcement in their telegram group saying: If you can not access the ( viabtc.com ) or App, please use the altenative domain name ( viabtc.net )
We will send you the detailed official announcement via email later this day.
Thank you for your understanding and patience.
Note: Kindly note that your mining or payment won’t be affected as long as your hashrates are valid. and previously they posted the following: Do not panic if you can not access the ViaBTC Web or App, we are currently working on this issue. Hopefully, it will be fixed later this day.
Kindly note that your mining or payment won’t be affected as long as your hashrates are valid.
Thank you for your understanding and patience. It's funny that they expect everyone to be on telegram, they should have sent out emails right after this shit happened, anyway, mining is going alright, heck, this is less scary than my experience with Poolin a while back, the pool was working just fine but my hashrate was showing zero.

As I just mentioned in the other thread: The issue is where their DNS servers exist.
If they where inside China (doesn't matter where the pool you mine to is) then the DNS is being manipulated by GFW and/or Aliyun.
This is still going on (I just checked it again now)
... and moving DNS outside China is not a 5 minute exercise.
