I don't know the real reason we are locked down either. I opened a new account with Zecco and was able to buy today.
I opened the account with Zecco just in case EESO would have a percentage increase like VW did last year. Sometimes crazy things happen and if so I'd kick myself if I couldn't participate.
Hopefully we'll know more in the future and see what is really going on with DTCC. IMO
