Network Delta issue to the point can't play

Sorry to hear it. Just to be certain can you please run a test at speedtest.net and post your results here? Include the Ping, Up and Download speeds.

While you're doing that hold the power button on the console for 10 seconds till it shuts down to clear the cache.

Avatar (beta) is Alpha SA, Alpha, Beta and Delta subset at this point in time

I participated in the Closed Beta without a single issue. Now I load in and I get the Mike and Delta errors constantly. I love how Ubi keeps pointing the finger at us, like its our fault lol. Now it sits at the loading screen @ 0%. I can't even load in now?!
Livid!! If this isn't resolved at all by Sunday, they just lost a pre-order

They used them for mere days/weeks not years.

How long had Subject Delta and Subject Omega been in commission? I can't remember from my play-throughs.

As an Insider, it passed through alpha, beta, delta and omega rings with no issue like this. Due to how few are reporting problems, would point to a hardware fault that coincided with the update.

It is rare that a software update would brick a console. Knowing which models of Xbox are involved would help.
