Here is topic for stratum.
https://github.com/MPOS/php-mpos/issues/1938

Badly configured....

This is even worse, as the "regular" miners don't get the correct share anymore..

But it makes me wonder.. Two incidents within short time, same coin...

This one is fake share/difficulty abusing, not related to dos.
Stratum need patch.

Most probably the same that DDoS'ed suprnova before.. Hmm.. Interesting...

Not sure if thats good or bad for Hiro...

Someone abusing hiro stratum pool.

Indeed, go mine P2P!

That's what I just posted, it was concerning the "big" DDoS. Spreading the Hash is always good, but it is better to have proper Back-Up Pools set

Spread the hash please

This was from the pool themselves:


That's what's going to continue to happen when we have one pool with over 50% of the network hash. They need to close registration and spread the hash to the other pools. Sadly, i was part of the problem so i've moved.

Yes absolutely, just checked the logs, no problems at all.. Did they disconnect completely ? Was the page reachable in this moment ? Maybe we have/had a routing issue ?

Thanks, that was the first time we were hit by a 60gbit/s DDoS..

This cannot be done by some "script kiddie"... Someone really wants the Hashrate go down...

Were you watching your miners lastnight?

I was and the stratum was up and down all night.

thanks for fixing any outage last days for me, except last 35 min, but just added failover server for sure

Not running good ? What was your problem ? Had no info/mail/Whatsover that something is not running fine.. Just checked my miners, also hashing on suprnova, no problems in the logs, just the ddos 30min ago ..

Sorry guys, we're back up :-)

Really had a funny evening tonight.. DDoS started with about 3 GBit/s on our stratum - nothing special, we have that every day.

The attacker(s) noticed we mitigated the attack, stopped it, and came back with 10GBit/s 30min later.. This was mitigated by our provider and our scripts again without problems. The attack stopped and came back with 30 GBit/s to all our ports, HTTP, HTTPS, Stratum, SSH etc. making the server practically unreachable. Fortunately our scripts took action and banned those attacking IPs, I never saw such a long Banlist in iptables :-)

After that worked out, the attacker came AGAIN, this time with 60bit/s to all our ports, from even more IPs, there where mostly from Russia and China which simply flooded our iptables completely. Our prov even contacted me and noticed me of the attack, they first though we're running a botnet-node on the server :-)

Nevertheless, they're now filtering the traffic at their Juniper Routers, so we're back in Business again and are really, really sorry for the downtime. Suprnova always does the best it can to fight against such attacks, we are having them everyday, but 60gbit/s is really A LOT :-)

Be wise, set-up backup pools, we're now protected on router-level, so we should be fine, but for safety reasons, PLEASE set-up back-up pools !

Thanks !

Yeah, just set it up for suchpool.

Suprnova hasn't been running very good these past two days... hoping this one is better.

Well i have 2 failovers, so no big deal
