Solana attributed the 17-hour outage it suffered last week to a denial of service attack targeting Grape Protocol’s first DEX offering (IDO) on September 14th.
In a blog post on September 21, the Solana Foundation stated that bots were spamming the network when Grape launched his IDO on the Solana-based decentralized exchange (DEX) Raydium last Tuesday at 12:00 UTC.
Botting activity overwhelmed the network with a transaction load of 400,000 per second, with Solana noting that “unlimited growth in forwarding queues and resource-intensive blocks” resulted in a series of forks being automatically proposed to the network.
The attack caused the Solana network validators to crash after running out of memory. As a result, the network was offline for approximately 17 hours on September 14th and September 15th.
The recovery was done in collaboration with Solana engineers and 1,000+ validators, passing a hard fork after being supported by 80% of the network’s active stakers.
“This has been a coordinated effort by the community, not just in creating a patch, but also in getting 80% of the network to consensus.”
The Foundation estimates that within 18 hours of Solana going offline, the network was patched, updated, and fully operational again.
The post added that the community is still working on delivering a detailed “technical post-mortem and root cause analysis report” that will be released in the coming weeks
