Article summary

A Belgian ISP has been under a 250 Gbps DDoS attack for days. The article does not provide details about the attack, but rather appears to be a collection of network status updates from the ISP. The updates mention various maintenance activities and resolved incidents, but do not discuss the DDoS attack. The attack is only mentioned in the title.

Main themes

  • DDoS attacks
  • Resource asymmetry
  • Botnets and compromised devices
  • New protocols and implementation
  • Proof of work and latency tradeoffs
  • Bandwidth asymmetry and its implications

What commenters say

  • DDoS attacks are still a significant problem due to the asymmetry in resource usage between attackers and defenders.
  • New protocols could potentially solve the resource asymmetry issue, but implementation and adoption would be challenging.
  • The use of botnets and compromised devices makes it difficult to prevent DDoS attacks, as the attackers do not pay for the resources they use.
  • Requiring clients to provide proof of work could help reduce the asymmetry, but this approach also has its drawbacks, such as increased latency for legitimate users.
  • The fundamental asymmetry in bandwidth between attackers and defenders makes it difficult to prevent DDoS attacks.
  • Some commenters argue that resource symmetry is not entirely achievable, as servers must always perform some work to determine if more work needs to be done.
