The only time bitcoin network was down was in August 2010 when a block with the largest number of total transaction inputs was mined and broadcasted, but some bitcoin nodes rejected it, causing an unexpected fork of the blockchain.
To restore a canonical chain, Slush and BTCGuild downgraded their nodes so their pools would reject the larger block. As such, the transaction doesn’t exist today, and neither does the bitcoins created by that block.
Bitcoin continues to run interrupted; however, “the Cloudflare DNS outage can be seen reflected in the rate of bitcoin transactions broadcast, presumably because popular web wallets became inaccessible,” said Jameson Lopp, co-founder, and CTO at Casa.
