The U.S. Senate is dealing with a “network outage,” the Senate Sergeant-at-Arms confirmed on Wednesday night.
The outage downed email addresses and some Senate websites on Wednesday and technicians are working to restore service.
“The Senate is currently experiencing a network outage including email and mobility and technicians are now working the issue,” Senate Sergeant-at-Arms Frank Larkin said through a spokeswoman.
Larkin’s office declined to provide additional information about the outage or whether it was caused by a cyberattack.
Four Senate staffers confirmed their emails were down and they were having trouble accessing some Senate websites, but they did not know what caused the outage.
One Senate staffer told CNN at 7 p.m. that email systems in his office went down at around 5:20 p.m. and were still down.
“It seems likely that that’s not just some routine maintenance,” he said, adding that he had not received any updates from the Sergeant-at-Arms office nor had he heard from the Capitol Hill Police Department.
At about 9:06 p.m., the Sergeant-at-Arms tweeted that the issue had been identified and engineers were working on a fix.
