Also seeing DDoS attacks on mining servers.

10 Gbps of UDP flood and ICMP flood.

Should not have any effect.

A DDoS attack was slowing down the Bitminter website. Apologies for that. It looks to be responding quickly again now.

Doesn't look like there's been another attack of any significance, so it could be something else that got your miner to move around. Nothing's been restarted or down though.

I don't know if it is the same people - I haven't received any message from them.

We had a DDoS attack today. UDP and ICMP flood.

The attack did not affect mining.

In case there are follow-on attacks, do let me know if you experience any connectivity issues.

Thanks!

Yeah, now the halvening is here. It will be interesting to see if the difficulty will drop some.

Thanks guys. Let's go for 5 more

Today marks 5 years of Bitminter.

Thank you to all who mine and have mined with the pool!

Seems OK now. Let me know if you are still having any issues.

Cloudflare (our content delivery network) is having issues in Europe. Our website is currently unreachable for some European users. Hopefully back to normal soon.

The famous "have you tried turning it off and on again"

If you send me a screenshot of the exact settings you are using to operator@bitminter.com I will check what's wrong.

In case you have trouble reaching the main server at mint.bitminter.com:3333 you can try us2.bitminter.com:3333 or eu1.bitminter.com:3333 as well.

Make sure you put a password. You can use X or 123 or whatever you want. Just don't leave the field empty - many miners refuse to mine if you do that. Our server doesn't care, so you can put anything in the password field.

Also make sure DNS is working on the miner. Without DNS the miner cannot look up the IP address for mint.bitminter.com. If you use DHCP it's probably ok. If you use manual settings, make sure you enter a DNS server. One option is to use Google's DNS at 8.8.8.8

At 84% CDF it means 84% blocks are found more quickly. But also 16% of blocks are slower. 16% is a lot. It's not something unusual.

Antminer S-series machines are stand-alone. You use a web browser to configure them and that's it. No need for any mining software (like Bitminter Client) on your PC.

Thanks for mentioning my pool jonnybravo0311 and GigaBit

I'd recommend for new miners to read a bit about 51% attacks.

Centralization is the Achilles' heel of Bitcoin. Certainly you don't want to make the biggest pools too big. But you also don't want one government to control all the hashpower. The situation with China today is not a good one.

I know many beginners are thinking they want to earn some bitcoins, they want their mining operation to be profitable and that's it. Truth is, you can do that with most pools, and doing things that are dangerous for bitcoin is not in your best interest.

Hmm, yeah, it would be possible. Interesting idea.

eu1 has looked stable to me for months. But it's always possible that something happens somewhere on the internet that results in some users not being able to reach a server. You could add mint.bitminter.com:3333 as a secondary on your miners.

No, that must be something else.

If you are using mint.bitminter.com:3333 could you try us2.bitminter.com:3333 or eu1.bitminter.com:3333 ? And if those work, please send me your IP address to operator@bitminter.com so I can check into it further.

In case anyone else running public services is interested:

We saw TCP SYN Flood, ICMP Flood, UDP Flood. Of note is that for the first time the mail server was also attacked. I think many forget that their mail server IP shows in their DNS. I always thought this would happen, but it took almost 5 years before it did.

We're seeing a ddos attack across all our mining servers simultaneously today. Let me know if you have any connection issues.
