Johnathan Amos needs to learn the difference between further and farther, or maybe it is a British thing.
The article mentions that the Ariane rocket is very reliable.
It's not the rocket I'm most concerned about, it is the payload bus that is the weakest link, as it is a one-time design and has never been tested by deployment.

Exactly. The telescope has been one long scary journey and unlike the Hubble telescope, if something goes wrong, it is too far away to service. I hope things go well. A lot of new science can be realized, but a lot things have to go right.

My JWST-anxiety - which has been growing steadily with the endless delays and mishaps of the past few years - is now ratcheting up noticeably by the day. Even if it survives launch, how am I going to endure the two weeks plus it will take to deploy, transit to L2, and begin checkout? :eek:

We all need to think positive things for the JWST! Only positive thoughts - the universe will take care of everything else! :)

"Engineers discovered an intermittent data dropout associated with a piece of ground support equipment after connecting the James Webb Space Telescope with its Ariane 5 launcher over the weekend in French Guiana. The observatory’s long-awaited blastoff will be delayed at least two days to Dec. 24 to troubleshoot the problem, the head of NASA’s science division said Tuesday. "

The launch has been delayed a couple of days because of a communication problem between the observatory and the launch vehicle system. Launch now scheduled for December 24th. More information on the new launch date will be provided no later than Friday December 17th.

The ultimate act of bad luck would be if the James Webb was destroyed by a fragment of that satellite the Russians used as a target for their ant-satellite missile

They might as well just go ahead and delay it one more day and shoot it off on Christmas.
