Several state unemployment-benefits sites are malfunctioning amid a rise in claims from Americans who are out of work because of the novel coronavirus.

New York, Oregon and Kentucky are among the states whose websites to register for unemployment benefits have experienced problems this week tied to unusually high traffic. Kentucky normally processes 2,000 jobless claims a week but received more than 9,000 claims on Tuesday alone. This is notable in that it signals jobless claims, a proxy for layoffs, are slated to rise in future weeks after remaining historically low before the new coronavirus started spreading in the U.S.

The web glitches have also created hurdles for many out-of-work Americans to apply for unemployment insurance.

States across the U.S. are closing down businesses, such as bars and restaurants, to curtail the spread of the coronavirus. Some states have also expanded unemployment insurance eligibility in response to the virus to include workers who are quarantined or who don’t have access to paid leave. These moves appear to be helping spur more Americans to seek unemployment insurance.

Unemployment-benefits applications filed this week won’t show up in the Labor Department’s weekly jobless claims report until next Thursday.
