SAN FRANCISCO (CBS SF) — PG&E’s website has gone down Tuesday morning due to what the utility said was a “high volume of traffic” from people looking up information related to a possible public safety power shutoff that could affect an estimated 600,000 customers.

With dry and windy weather forecast in PG&E’s service area later this week, the utility is warning more than 250,000 customers in the Bay Area and about 350,000 elsewhere in Northern and Central California about possible preemptive shutoffs to prevent the sparking of a wildfire.

“We are currently experiencing high volume of traffic to our website & understand your frustration w/ the delay of accessing .PSPS related web pages,” PG&E wrote. “We apologize for the convenience and thank you for your patience as our team is working as quickly as possible to restore access.”
