Banking services at Indian Overseas Bank, which had been hit across all its branches in the last few days due to a technical glitch in a server at the headquarters here, have been sorted out, bank sources said.

Considered one of the largest public sector banks with 3,000 branches nationwide, the glitch “largely affected” transactions, hampering day-to-day operations, they said.

IOB Chairman and Managing Director M Narendra said services were affected on Monday and restored on Tuesday.

However, for the fourth day today, banking as well as ATM services continued to remain affected.

A senior IOB official told PTI that “the issue was sorted out and system is working today“.

The bank has about 2,000 ATM networks across the country.
