blockcrawler was / is not down .. ? it was down yesterday for about 3 or 4 minutes as i had to restart the wallet.
(got a version warning aswell, but that seem to have vanished.)
http://blockcrawler.rf.gd/ is down for me as well. uBm can you report on the status of this? And for future reference is there a repo on github for your blockcrawler code/config?
Blockcrawler is from github allready, i am fixing the one or other thing on it, and i will push it as soon as possible to a repo.
I am not really happy with it as it shows neither the TX nor the BLocks really well.
Also the api had to be disabled as there where more then one backdoor in it.
for address search , what would be fine - there is need of a real good mysql data server with high bandwith and hdd space.
for the easy blockcrawler i will add you on github as soon as it´s up with fixed source ( can take some days untill i think its ready).
for p2pool:
i am testing the merged mining solution at the moment, the changes i did at this time to the p2pool chain is as far as i understand it, a good one. i had people mining, and they have gotten payouts many hours after they where gone.
The actual standard is set to 24 hours, which is way to high. currently testing with 6 hours. i also did a add on possibility to transmit the miners second Coin address (for merged mining) that needs still work though.
I added a 3rd char which can be placed behind the primary coin address ( Sign "@" ) which splits primary address from secondary miners address. Needs testing. at the moment it is only in the log files and on p2pool screen. as it will need manual payout and control of the secondary coin address. (patron_sendmany does only show a string for paying out, but not for secondary coin - only primary coin) - that needs work.

traditionally p2p pools are for lesser coins with small payouts so i can see 24hrs being the defaults for payouts . you will need alot of bandwidth for MM to see a result in the near future if you think you are ready to test ill throw a rental rig your way
