Rocket Lab experiences a tank failure during Neutron pressure test

According to an update posted yesterday, during a pressure test of a first stage tank for Rocket Lab’s new Neutron rocket, the tank ruptured.
As the company pushes Neutron to the limits and beyond to qualify its systems and structures for launch, qualification testing of the Stage 1 tank overnight resulted in a rupture during a hydrostatic pressure trial. Testing failures are not uncommon during qualification testing. We intentionally test structures to their limits to validate structural integrity and safety margins to ensure the robust requirements for a successful launch can be comfortably met.
There was no significant damage to the test structure or facilities, the next Stage 1 tank is already in production, and Neutron’s development campaign continues while the team assesses today’s test outcome.
The team is reviewing the Stage 1 test data, which will determine the extent of the impact to Neutron’s launch schedule.
The company was aiming to do Neutron’s first launch in the first quarter of this year. Though the press release is vague on this point, its language suggests the rupture did not occur at the expected maximum pressure, but took place sooner, at a lower pressure level. If the tank failed at maximum pressure, then there would be no need to reconsider the launch schedule. A failure at lower pressures would require changes in tank design, and thus a launch delay.
The company says it will provide an update in February, which further suggests a launch in the first quarter is now unlikely.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Wasn’t this very similar to a Chinese rendering?
As the saying goes, “that’s why we test.” Rocket Lab’s record of recovering from anomalies is a lot closer to that of SpaceX than it is to, say, ULA or Boeing. This will almost certainly delay Neutron’s maiden flight test, but probably not by more than a couple of months.
I just don’t trust composites.
Beal was going to use carbon fiber too, right?
I don’t think high test peroxide likes that taste.
Composites have been in extensive use in aviation and space for many years. They are not intrinsically an issue.
