The US government has raised concerns about Russia's decision to block access to LinkedIn in the country.
Russia began blocking access on Thursday after a legal case against the firm which it said was not abiding by recent rules that data on Russian citizens using overseas web services must be hosted in Russia.
LinkedIn had appealed, but lost the case and its six million users in the country now cannot access the site.
Maria Olson, based in the US embassy in Moscow, issued a statement in response saying that Russia's stance is worrying.
"The United States is deeply concerned by Russia’s decision to block access to the website LinkedIn," she said, as reported by Reuters.
"This decision is the first of its kind and sets a troubling precedent that could be used to justify shutting down any website that contains Russian user data."
LinkedIn confirmed to V3 that users reported being unable to access the site earlier this week, but said it was hoping to come to an arrangement with authorities in Russia.
“We are starting to hear from members in Russia that they can no longer access LinkedIn. [Russian communications regulator] Roskomnadzor's action to block LinkedIn denies access to the millions of members we have in Russia and the companies that use LinkedIn to grow their businesses," a spokesperson said.
After losing the court case last week, LinkedIn issued a statement saying that it will work with Roskomnadzor to resolve the problem.
"LinkedIn's vision is to create economic opportunity for the entire global workforce. The Russian court's decision has the potential to deny access to LinkedIn for the millions of members we have in Russia and the companies that use LinkedIn to grow their businesses," the firm said.
"We remain interested in a meeting with Roskomnadzor to discuss its data localisation request."
The problem will no doubt be on the radar at Microsoft, which has agreed to buy LinkedIn for a huge $26.2bn in a move widely seen as a chance to grow the firm's data insights on business professionals the world over.
However, Microsoft faces other battles around LinkedIn, having had to agree to concessions from the European Commission over the deal.
