PPS Fee Increase - Next 24-36 Hours

As posted previously in the 51% Mitigation Plans, BTC Guild will increase its PPS fee if it reaches 40% of the last 2016 blocks.  Right now BTC Guild is at 39%, and with many pools having issues this last week, it is very likely BTC Guild is going to hit 40% within the next 24-36 hours.  There is a modification to the plan to make this a more urgent issue.  The fee increase will affect ALL PPS users immediately.  PPLNS is not affected.  Originally the plan was only targetting new users, and then old users after a difficulty change.  Unfortunately this is hitting almost immediately after a difficulty change.  Waiting until the following difficulty is simply not an option at this point.
...
Say ASICMINER moves and BTCGuild goes below 40%, will things go back to "normal" until the next wave of hash is added? (like when ASICs really start shipping in mass)

The current plan is that the PPS fee will remain increased until a large buffer has been created to keep this situation from happening again.  At this time it will either be 30% or 35% of the last 2016 blocks, depending on how fast it drops, and what happens when more ASICs launch.  The last thing we need is the fee to bounce up/down every month.

PPS is something I've been growing a bit concerned with as prices rose.  Those who have read Meni's paper on bankruptcy at PPS fees and the buffers required know that even at 5%, a very large buffer of coins is required to reduce the odds of bankruptcy to near-0.  It's quite frankly very intimidating to need to keep so many coins in reserve at $100+/coin, when only a few months ago it was less than 1/5th the USD$ value.

For the curious you can use Wolfram Alpha to compute the buffer from Meni's paper. At 5% PPS, with a 1 in 1000 risk of ruin, you need 1,726 BTC in reserve. Replace the '1000' and the '0.05' in that URL to change the risk of ruin and percentage fee respectively.

Frankly, I would just as soon see PPS eliminated completely.

If any individual miner cannot accept his personal risk/variance, then, IMO, he is playing the wrong game. I see no reason any pool operator should accept that risk of variance.

Huge burst of packet loss to my server in Dallas which runs the website proxy.  I'm hoping its datacenter related, but it could be a DDoS starting up.

Sorry for the website downtime earlier, which also affected ~50% of getwork users.  The 'www' subdomain was attacked, and being on the same switch as getwork caused both to go down.  I moved www to a new proxy server and nullrouted the old IP about 30 minutes ago.  Everything looked fine, but I missed one of the access methods.  btcguild.com worked, https://btcguild.com worked, https://www.btcguild.com worked, but just plain www.btcguild.com did not work.  That has been fixed.

Website is a bit laggy because during the attack I had to toss up a very quick low end VPS to run as a new proxy to the backends.  Whenever the pool is attacked, I use these lower end proxies because they are quick and easy to launch, and do not hit the pocketbook too hard like Amazon EC2 does.

I'm working on launching a new proxy today that should speed up the load times.

New proxy for the website is running, should be a bit faster than it has been the last 24 hours.  I've also optimized a few pieces of the website to cache values and speed up the load time of some pages.  There were previously a lot of earnings detail being calculated/stored regardless of the page you were looking at due to the 24H earnings statistic.  24H earnings is now cached for 30 minutes at a time, and the other earnings/payout information is only generated on pages which require it.

PPS Fee has now been increased to 7.5%.  This was done by moving all shares submitted this difficulty (10076292) down to difficulty 10076291, so you will get a few satoshis extra for work done so far this difficulty.  All new PPS shares submitted will now be credited as 7.5% fee at the current difficulty.

I'm testing CloudFlare on the website.  SSL is currently a bit screwy.  The cloudflare cert you're seeing is OK.

would it be possible to implement an email alert when a specific worker goes down after a set threshold in Mhash?

SSL issues should be over now (they were issuing a temporary certificate after I turned on SSL).  If you close your browser and open it again, it shouldn't be showing any warnings anymore.  Site is loading a lot faster now than it was through the use of reverse proxies before.

As expected, some people have decided that the solution to a fee increase is to attempt to DDoS the pool.  Sorry for the connectivity issues the last 30 minutes.  Things should be back to normal at the moment.
