The Health Ministry website (Hebrew link) that issues the “Green Pass” for vaccinated Israelis crashed and has been unable to issue the certificates for hours, the night before the passes are supposed to be put into use.
On Sunday morning Israel will roll back some of the major restrictions imposed in late December as part of its third lockdown, with stores, gyms, hotels and other venues allowed to reopen, for Green Pass holders.
People who have recovered from the virus can also get the pass.
The Health Ministry launched the long-awaited program on Thursday.
To be allowed to open Sunday, relevant businesses must scan people for the pass and only accept those carrying it.
The pass has seen additional problems, with reports of thousands of people scheming to forge the pass to illegally partake in newly-allowed activities.
