IndiGo operations hit; The airline's passenger system server is idle for more than 30 minutes.

BENGALURU: Thousands of passengers who were going to travel with Indigo Airlines across the country were stranded on Monday after the airline's passenger system server, Nita, went on the road for more than 30 minutes early in the morning, due to technical problems. Passengers in Bengaluru, Chennai, Mumbai, Pune and Hyderabad were the most affected and they waited in long lines near the Indigo counters at the departure terminals, waiting for the registration process to begin for almost an hour.

The airline’s server was down between 4:29 am and 5:07 am, on Monday said Indigo officials, while confirming that the system is now up and functioning normally. During this time, manual boarding passes were issued to passengers at airports, including the Bengaluru International Airport.

However, passengers quickly went to social networks to complain about the server's failure and how they were made to wait almost an hour at the airports in the country.

“@ Indigo 6E systems/servers are down at @bengaluruairprt.we (passengers) are waiting in long que since almost an hour now. The entire indigo checkin counters are jam [email protected] Indigo 6E please update and help..,” tweeted a passenger Amit Baby Oomen.

"@ Indigo 6E @BLRAirport @HardeepSPuri @MoCA_GoI due to indigo server issue hundreds of peoples are stranded in the airport," tweeter Balaji, a passenger, from the Bengaluru International Airport.

"Dear @ Indigo 6E What's happening here in Hyderabad. All systems are down and not received the boarding pass till now (waiting since 4am). Flight @6.15am. A huge queue before me... @RGIAHyd @HardeepSPuri @PMOIndia," tweeted Subhash, a passenger who was departing from the Hyderabad airport.

"@ Indigo 6E Chennai airport systems down? Having horrendous time. Standing in queue," tweeted Kasturi Srinivas, a passenger departing from the Chennai airport.

A hard copy of the boarding pass is required at the Mumbai airport. Indigo is asking all passengers to wait in line as the server is down and more than 700 people in the queue, Pankaj Mishra tweeted, from the Mumbai airport.

Indigo , in a statement said "Due to some technical reasons, Indigo server at Bangalore airport was down from 4:29am to 5:07am this morning. The server is restored and functioning normally. We regret the inconvenience caused to our passengers.”

In April of this year, in a similar incident, due to a failure in Air India's passenger system server, SITA, more than 155 flights were delayed worldwide, leaving passengers stranded at national and international airports.
