Do you find your pool is subject to more DDoS attacks than most, or is it pretty common?

Some kind of attacks are pretty common and all major pool operators have a lot of experience in fighting them :-).

I also received notification from server provider that they're changing edge router which suddenly failed (both 10G cards, what a chance?). Traffic is now going over backup router, but I expect some routing issues during the maintenance.

Hey Slush did you make any changes to the system around March 16  I'm getting the 100% cpu bug on my miners but only using your pool it started around the 16th or early on the 17th.

See my thread here for more details https://bitcointalk.org/index.php?topic=74419.0

This is very interesting, but some other people come from other pools to my pool exactly because they have no 100% cpu bug with me :-). I mean - there's probably some strange issue inside guiminer which can be triggered by anything like faster/slower responses etc. I didn't changed mining part since March 16 and I even cannot imagine how can I affect this bug by change inside the pool...

It's called variance. Unless you have connection problems it is very normal that payouts vary on a daily basis depending on pool luck.

I have a problem with changes in payout according the duration of the round: on short rounds I use to get about 30% less of what I proportionally should.
See an example below. I mine 24/7 with 1.3 Ghs, so I should average: 49*(1.3/1209)= 0.05268 BTC per block, but if I calculate an average of all my BTC rewards in my statistics I obtain: 0.043032276, that is I am averaging a -18.3% BTC reward. Any comments?

Yeah, same observation here. Either people are poolhopping anyway, or the algorithm is strongly favoring faster miners.

How do you mean "people are poolhopping anyway"? When did they stop?

Chaang Noi (Goat)'s fault ! He made a pool of hoppers. You can see the variation of MHASH/s on the pool on my post.

There was a long discussion on this and slush is working on a solution (new mining server).

Goat all by himself? No. Slush gets hopped by way more than 200Ghps. There's plenty out there that do it.

The solution hopefully would be using a hop proof algorithm.  Score based pools can still be hopped, tweaking the score isn't going to change that.  It may for a while and then hoppers will adapt.

Given PPLNS, SMPSS, PPS, and DGM are all well tested and hop proof prop and score based pools are an anachronism.

You read too fast. He made a Pool of miners ... that mine on Pools ... hopping between them (MINECEPTION). => a pool of hoppers !

You think too slow. There's more than one 'pool of miners hoppers' out there and slush is being hopped by around 500 - 600 ghps.

SMPPS is not hopping-proof and is not sustainable.

Shift- versions of PPLNS and DGM are probably more scalable.

I've actually noticed a bigger difference based on the duration of the round and I'm right around 2ghash.  I'll average about .07 on most rounds, but on shorter round, generally under 5 minutes, I'll average around .03.

The only reason I haven't said anything sooner is because this conversation has come up before.  And it was generally attributed to pool hoppers.

If the hoppers contributed to the total share of the initial 5 minutes, they increased pool's hashrate thus contributed to the success of finding the block.

But where do those hoppers go leaving the pool? solo?

Im not exactly sure as I've never actually hopped myself.  But I'm fairly sure they come onto the pool at the beginning of a block.  And they will stay there until the current block reaches a preset amount of shares.  Once they hit that number of shares, they move on to another pool that is just starting a block.

If they are on Slush's pool, and he finds a block within a couple minutes, I would imagine that they would hang around for the next block to see if they can cash in on that one too, but eventually they will reach that preset number of shares (or possibly preset block running time?) and move on to another pool.
