This question has me wondering constantly as I try out over 30 different pools for various currencies.
What is so hard about making a good pool? So many bitcoin pools work flawlessly day after day maybe 1 interruption a month.
But trying to find a pool for:
CHNC
PPC
TRC
LTC
FTC
All I am ever left with is a pool that works for maybe 12 hours and then dies constantly for the next 12 hours.. I find a new pool and the same thing happens again!
Using the excuse of DDoS attacks is highly unacceptable as while it is valid for some there is no way everyone is DDoSing every alt coin pool ever. What gives?
It's very easy to DDOS all the pools when there's not that many for alts. For a decent sized botnet it is no problem. A few days ago pools were getting hit by over 8gbit of traffic. Nearly all providers will null route your IP automatically given that size of attack, then you are looking at downtime of 12-24 hours until the next attack.
The big Bitcoin pools are making quite a lot of money in fees and can afford better protection, and therefore are more resilient against these type of attacks.
