Title: BlockExplorer.com and BlockChain.info out of sync?
Post by: BrightAnarchist on March 01, 2012, 09:28:52 PM
I don't want to reveal one of my addresses, but it seems that these two websites are reporting different transactions at present. Specifically, there are txs on blockchain.info that have not appeared on blockexplorer.com.

Any ideas? Thanks

blockexplorer.com is at least 60 blocks behind blockchain.info right now.

Blockexplorer is at 169217, Blockchain.info is at 169277.  If your transaction is between those you should expect to see different results.

BlockExplorer is now a lot more that ~70 blocks behind: 182750 vs 183442

And it looked as if BlockExplorer even regressed! I grabbed a random address from BlockExplorer yesterday for testing purposes, 16A2heKS1zf4D3pHhwoHEweLzvBzExPtRS. Yet today when I go to BlockExplorer, it no longer has the block that includes that transaction, 182973.

Hmm...might be worth running a blockexplorer mirror myself. BlockChain and BlockExplorer are pretty darn useful.

I'm trying to fix it now. My PostgreSQL database's size on disk quadrupled for some reason, almost filling the disk and causing problems.

"Some reason" is probably satoshidice and their many tiny transactions.

I don't think so. My other BBE instance has a database size of 22 GB, while the main site's database with the exact same data is ~90 GB. I think it's something fixable. Right now I'm vacuuming the database to see if that helps. If that doesn't work, I'll ask the people on #postgresql if they know how to fix it. If not, I'll reset the database.

Is this other instance + the main instance behind a load balancer?

EDIT:

That is, are they running off different IPs, and one is randomly shown when querying blockexplorer.com?

It used to be set up that way, but my personal BBE instance is too slow to handle any significant percentage of the traffic nowadays.
