New Hillary Clinton e-mails released in a late-night document dump Monday reveal how the former secretary of state’s use of a private e-mail account sowed confusion in the State Department, with government IT professionals unaware that she was using a private — and apparently buggy — computer server to conduct official business.

On February 27, 2010, State Department computer technician Christopher Butzgy sent an e-mail titled “E-mail test” to Clinton’s private e-mail account. “I work as a help desk analyst and it has come to my attention that one of our customers has been receiving permanent fatal errors from this address, can you please confirm if you receive this message,” he wrote.

Clinton did not confirm, instead forwarding the e-mail to top aide Huma Abedin. “Do you know what this is?” she asked.

“Ur email must be back up!!” Abedin replied. “What happened is judith sent you an email. It bounced back. She called the email help desk at state (I guess assuming u had state email) and told them that.”

“They had no idea it was YOU, just some random address so they emailed,” Abedin continued. “Sorry about that. But regardless, means ur email must be back! R u getting other messages?”

#share#“I’ve gotten some messages from yesterday — how about you?” Clinton said. “Nothing,” Abedin replied.

It’s not the first time Clinton’s e-mail server apparently stopped working. In October 2012, Abedin complained to Clinton that her e-mail account “has been down since last night.”

#related#With State Department technicians apparently unaware of its existence, it’s impossible to determine who fixed Clinton’s faulty e-mail system. In June, David Bossie, head of conservative group Citizens United, raised questions about the server collapse and its national-security implications. “Huma is talking about her e-mail being down, about the server being down,” he said on Fox News in June. “Who services the server? Does the geek squad show up and just fix it in Chappaqua? I don’t think so.”
