I'm assuming this is another case of ransomware which has probably already been paid. The shutdown is because billing has been disabled. This was the case with The Colonial Pipeline cyber attack.
That would help explain the scarce meat available at BJ’s last week.
This cyber attack was Sunday. I don't like BJ's. I won't pay for the right to shop somewhere. That goes for Amazon Prime as well. My brother gave me a Sam's Club membership for my birthday back in November. I've been there 3x this year.
