Greetings,
TLDR: There was a DDoS along with some data center network issues last night. All is well now. No Eligius servers were compromised.
well, that's not all, right?
we lost a block due to...things, which may or may not be directly related to ddos.
did not exactly get the point why the block was not submitted on a timely basis ("because of extreme latency at the datacenter").
i don't think that the datacenter was ddosed, right? maybe you need to be at a better datacenter?
My personal loss ~$25
oh, well
So,
I publicly post a detailed explanation of exactly what transpired that day (over two weeks ago now) with to-the-minute timestamps of everything that happened... and that's not good enough for you?
Exactly what I posted is exactly what happened. The loss of primary connectivity at the datacenter caused what would have normally been an easily filtered DDoS attack to severely saturate secondary connectivity for the entire datacenter with
hundreds thousands of machines competing for tiny slices of remaining bandwidth with latency as high as two minutes for a short period. Nothing else that could have been done to prevent this. Aside from putting in my own 4G LTE backup connection or having some alternate connectivity for the block submission paths in the future there would be nothing to be done to fix against this.
The arrangement I have with the two main datacenters that Eligius uses keep Eligius's cost well below what they should be for very stable connectivity and hosting. I'm talking something like 10% of retail here, and 100% of donations go to covering hosting. Sometime's it's not enough, and they let it slide because they know what is being run. They essentially subsidize our hosting a bit asking for nothing much in return mostly due to my prior unrelated relationships with them. Get a better datacenter? Good luck finding better ones than these at the prices we pay for hosting all of the equipment needed for Eligius along with the massive amounts of bandwidth needed for normal operation AND mitigating DoS attacks.
Put it this way. In the past two years Eligius's downtime due to datacenter issues: About 45 seconds, 100% of which was from the incident two weeks ago that was well beyond their control. That's 99.99993% connectivity uptime. Electric power has also never been down for a single second in the nearly full decade that I've had a relationship with them. I have a personal server there that's highly outdated with an uptime of something like 1500 days.
On top of that, I've gone out of pocket on 4G LTE backup connectivity for Eligius's rack (plus some unrelated servers) to ensure that this is extremely unlikely to happen again by always submitting blocks via the LTE connection in addition to the normal channels.
If you're asking for more than that from a 0% fee pool, please just mine elsewhere.
