Grace from the support team was awesome. She helped me with my transaction which didn't go through due to low fees. I will recommend Beaver Dealer to all my friends, they are the best. Thanks Grace!
Public blockchain platform Solana (SOL) went down again in the early morning hours on Tuesday, according to several community members, as well as the major crypto exchange Coinbase, which warned users that Solana was experiencing ‘’network-wide degraded performance’’. (Updated at 8:38 UTC on January 5, with comments from Anatoly Yakovenko. Updates in bold.)
Reportedly, an attacker used spam to conduct a distributed denial-of-service (DDoS) attack, which occurs when multiple systems flood the bandwidth or resources of a targeted system. Ostensibly, it took the team five hours to resolve the issue.
On its part, Coinbase too marked the incident as resolved seven hours after it's initial statement.
Solana's Twitter account has not made a statement on this issue by the time of writing, while their website shows all systems operational and a 100% uptime in the past 90 days.
In the early hours (UTC) of January 5, Anatoly Yakovenko, Founder and CEO of Solana Labs, denied the report that Solana went down due to a DdoS attack.
“That’s not at all what happened,” he commented. “There was some congestion due to mis metered transitions, and some users experienced their txs timing out and had to retry.”
Solana, released in April 2019 and known as an "Ethereum Killer," has a low fee of USD 0.00025 per transaction and is capable of processing an average of 2,000 transactions per second.
However, this low fee has proven to attract bad actors who overwhelm the network with hundreds of thousands of transactions at a considerably low price.
Back in September, Solana suffered an 18-hours long network outage as the result of a massive increase in transaction load, which reportedly “flooded” the transaction processing queue. The project had to hard fork to resolve the issue.
At the time, the CEO of Solana Labs, Anatoly Yakovenko, acknowledged that the issue was caused by bot trading, adding: “better now than when its a billion users.”
In mid-December, Solana slowed to a crawl again following a token sale on Raydium, a Solana-based automated market maker (AMM) and liquidity provider.
