Did Bluesky Actually Suffer a DDoS Attack Last Week?

In today's brief 'final update' they dropped the claim the cause was a "sophisticated Distributed Denial-of-Service (DDoS) attack", and clearly do not want to discuss the subject any further.

But is this OK? Do Bluesky users have a right to truthful information about the outage and why it was so severe?

In April 2025, Bluesky attributed an outage to a DDoS attack only later to reveal that it was not.

Attached: 1 image Bluesky Issues "Final Update" on April 15 Outage - Shares No Details - Drops DDoS Claim What is notable about this terse update is the lack of information, and no mention of a DDoS attack. People had expected some form of incident report. What actually happened? What actions were taken to restore service? Contributing technical & systemic causes? Actions taken to diminish likelihood & impact of future similar recurrences? (See reply below for official comms so far.) #Bluesky #DDoS

Some are saying that dropping the mention of a DDoS attack does not mean that it did not occur. This is absolutely true, but it does raise questions.

@iampytest1@infosec.exchange Completely agree that not mentioning the attack is not per se evidence that it did not occur. Rather, dropping the claim of a DDoS attack raises the question of whether it did occur. Bluesky has made this assertion, so it seems incumbent upon them to back it up with some evidence. The fact that they do not seem to want to do so, or answer any of the legitimate questions you raise above, is troubling. I hope tech media does not simply let the matter drop.
