So thats why people with matrix.org accounts stopped responding to my messages...
Nice mention of the benefits of decentralization.
The incident demonstrates the benefits of a decentralized system. Users with their own homeservers aren't affected, nor are organizations such as Element, which have customer deployments that utilize the underlying technology.
One homeserver going down does not affect the rest, even one as visible as Matrix.org.
Matrix has become increasingly important in recent years as public and private sector organizations seek to reduce their dependency on centralized messaging services that might not meet sovereignty or privacy requirements. The Matrix.org outage, while embarrassing, serves to highlight that a decentralized approach can protect users from whoopsies on the part of those who run the service.
