Solana network almost halted - 28.83% of staked SOL went delinquent

[RGBTC]

As the title says, this is all due to a routing error at Teraswitch. Solana briefly touched the remaining 19.9 million SOL before reaching the finality halt threshold of 33.33%⁽¹⁾.

2/ It was a routing fault at @Teraswitch. They’ve published a writeup already, which is more than most providers manage. A default route out of their Miami site got advertised with the attributes stripped off it. A route reflector in Amsterdam then handed it to every site in EU.
3/ The edge routers there treated it as their own local default and preferred it over the real one. The core underneath refused it as invalid. Twelve sites ended up with nothing valid to forward to.
LON1, AMS1-3, DUB1-2, FRA2, SGP1-2, TYO1-3. North America never noticed.
4/ Took them ten minutes to find it. Traffic was back by 04:16:15 UTC. Miami is still off their backbone while they work out what generated the route.

Multiple ASN providers experienced simultaneous outages, revealing hidden infrastructure dependencies beyond simple hosting share. The largest ASN holder was hosting over 27% of total staked SOL at 94%⁽²⁾. The new requirement of a Maximum Concentration Limit of 25%⁽³⁾ actually saved the network this time, but it looks like it has to be tightened even more, for example to 10% for each providers.

Altcoin are so funny man , they keep saying they are decentralized only to find out that more than a quarter of their total validator use same infrastructure provider, a routing error is enough to almost cripple the entire blockchain. The worse thing is, solana is not the most centralized blockchain, there are blockchains with less than 40 validator and the validator knows each other, almost like private consortium and there is a blockchain that only have single sequencer to run the entire blockchain that secures $12.7 billion TVL...

AFAIK, the 25% ASN limit only enforced to validator with delegated funding from the Foundation which is 50% of the active validator, the other 50% are free to choose where they run their validator, I agree with the 10% cap, it should work better than the 25%.

The centralized altcoins always find a way to hide it and make sure that they are the ones making profit. I remember when creating new altcoins was a trend, they came up with the idea of "premining" the coin so that they could own a large amount of the supply and dump it on the market to make profit. Obviously people caught up and started hating premined coins. But the scammers came up with a solution "shadow mining"! They did the premine but in a covert way so that people could not easily figure out and continued scamming them.

Things haven't changed much, they keep finding new ways to create centralized shitcoins to make money. If you compare what is said about majority of altcoins in their advertisement with what really happens on the chain you'll see 90% of it is lies.

This is why Bitcoin is so good and strong. What is said in the whitepaper and what is actually happening on chain are the same. There is no hidden agenda, no hidden centralization, no hidden premine, etc. So bitcoin keeps growing every year while these shitcoins shrink...
