Binance has now issued a statement on its website, saying that the exchange has “completed its system upgrade and we expect all trading activity to resume at 10:00 AM (UTC).”
Moreover, the announcement relayed that during the 60 minutes prior to trading restoration, users will be able to cancel orders, process deposits and withdrawals, and conduct any other account functions without restrictions.
In an effort to compensate users for the lack of access to their accounts, Binance has also announced that all users will receive a 70% discount on trading fees (0.03% on all trades, 0.015% with BNB). The discounted fees will remain in effect until February 24, at 00:00 AM (UTC).

Despite claims that unforeseen incidents caused the malfunction, CEO Zhao Chengpeng tweeted a more detailed and technical explanation for the incident, specifying a server issue causing data sync failure.
We experienced a server issue on our replica database cluster, causing some data to be out of sync. Need to fully resync from master. Due the size of the data, it will take several hours. No data is lost. We appreciate your understanding and support.

Shortly thereafter, John McAfee sent a tweet claiming that rumors had surfaced, which appeared to indicate that the true cause behind the lack of access to the exchange was that the exchange was hacked.
These issues were swiftly denied by Binance, denying the claims in a fast reply to McAfee’s tweet, asking him to refrain from spreading false and unproven information.
Binance has not been hacked. Please do not spread false information. If you want to keep updated on the status of our system upgrade you're welcome to follow @cz_binance or @binance_2017
