Could the recent stats outages at Free-DC be due to a similar DDOS as was observed at PrimeGrid? Seems to occur every Friday evening/night.


I have no idea what the cause is, but I don't think Gridcoin accesses any third party sites.


See I think that would solve the problem, if Gridcoin itself got the stats from a stats site, or even the Projects themselves, and then spread them out to their users with GridCoin itself then being the OFFICIAL numbers people get paid from. That way they do one connection to the stats site, or Projects sites, download the data and then the users get it that way. Probably alot more work on their part and the daily numbers would fluctuate a bit more but it would solve the apparent DDOS attacks.


That's what they've been working on since June. If you want to contribute to their effort, this is not the place to do that.

You also need to keep in mind what TDP stands for, and what it's used for.

Most importantly, it's most definitely not what would be most useful, which would be something like "Max Power Rating". There's no such thing.

TDP (Thermal Design Point) is intended to be a rating used to determine what kind of heat sink you use. On high end chips, nobody in their right mind, especially crunchers, is going to use the stock heatsink. You're going to use something much more capable than what's indicated by the TDP.

In practice, TDP is used as a marketing tool, period. It's on a par with other slogans put out by marketing departments. Buyer beware, indeed.

The only time my Haswell -- at stock clocking except for the memory -- runs below TDP is when it's running a CPU sieve.

Posted 5 days ago by Profile Michael GoetzProject donor
If you've been experiencing slow-loading forums at PrimeGrid, or, for that matter, any BOINC project's forums, the reason is because the Free-DC website has been down a lot recently.

Many people use forum signature images from Free-DC, which your browser loads when it displays forum messages. If Free-DC is down, your browser has to wait for the image request to Free-DC to time out. That's why the forum pages load slowly.

If you want forum pages to load more quickly, go to the Community Preferences page and check the "hide signatures" box. Don't forget to click on the "Update" button at the bottom.

I think this is unfortunate, but its up to each project to do what they want.

I don't like the description of "DDOS Attack" though, Gridcoin is not a single entity it's a collection of individuals, individuals were downloading stats for the purpose of accessing the stats, not to cause an attack. It so happens that the concept of decentralization is critically important in cryptocurrency, to stop cheating as it happens.


Actually, in this case, it was a DDOS attack coordinated by a single entity. Again, it wasn't intentional, but it was a coordinated attack nonetheless. The Gridcoin "neural net" was designed so all the individual computers would access the statistics at the same time. It wasn't "everyone acting on their own". It was, quite literally, "everyone acting as one".

To be clear, the fault lies with the people (programmers) who designed the Gridcoin system, not the users. The users are 100% blameless.
