On Wednesday morning, the Lodi Unified School District took to social media to announce that it had experienced a computer network disruption on October 3, which prevented staff from accessing some files and systems.
A third party has been hired to help staff at the district’s technology department investigate the extent of the shutdown and restore access to affected systems, the social media post said.
The district’s website was unavailable Wednesday morning, the phone systems at five schools were down, and staff were unable to use email accounts.
The telephone lines to the James Areida Educational Support Center were restored at around 10 a.m.
“Our technology department is working diligently to protect all student data and personal records,” the district said. “We do not have an estimated timeline for when our network will be operational again. “
The district’s website was back online at the end of the day on Wednesday.
Lodi Unified’s network shutdown came just days after Monday’s Facebook outage, although the two events are unrelated. The Facebook outage lasted about six hours and prevented users from refreshing feeds or sending messages.
The social media giant’s vice president of infrastructure, Santosh Janardhan, said in a blog post Monday night that the outage was caused by “configuration changes on the backbone routers,” but did not explained in more detail what these changes were.
Facebook, along with its affiliate networks Instagram and WhatsApp, ceased to function shortly before 9 a.m. on Monday.
In April 2019, the city of Lodi was the victim of a ransomware attack that hampered its phone lines and financial data systems.
The attack occurred after an employee opened an email attachment that sent malware through the city’s computer network. He encrypted critical files that took several key phone lines out of service, including the Lodi Police Department non-emergency number, the public works emergency breakdown line, and major town hall and finance numbers. .
The hackers demanded that the city pay 75 Bitcoins – or $ 400,000 – in exchange for the encryption keys that would free the servers.
The city did not pay the ransom, instead rebuilding its systems from backup servers.
The following December, the town of Galt suffered a similar attack that cut several telephone lines and blocked access to employee computers.
This attack was also triggered by a Galt Town employee opening an email attachment that sent ransomware all over the computer network. He turned off the same phone lines – the Galt Police Department non-emergency number, the Galt Public Works emergency breakdown line, and the main Galt Town Hall and Financial Department numbers.
And like the Lodi attack, the pirates demanded a ransom from the town of Galt, which was not paid.
