Looks like it. When I first loaded HN 2 minutes after this outage started, the story was #2. Then I refreshed after 3 minutes and it wasn't on the front page at all. Used the search tool to find it and then upvoted.
Looks like somebody wants to keep this quiet. 65 points in 12 minutes is good enough to be #1.
Outages without any information are not intellectually interesting, and typically neither are the discussions that follow.
It is infeasable to keep a global outage quiet.
High comment rates can also trigger the "overheated discussion detector", which will downweight a submission.
Perhaps the HN mods should do something about that then.
If you see something like this and you think it's in error, you can let them know and they'll likely be able to respond more quickly. There's a contact link in the footer.
You're joking, right?
No, I'm not. In my experience the mods are quite responsive, and have explained site behavior on more than a few occasions. They've also adjusted flags and weights of submissions if they identify an issue.
