Flipkart customers are reliving the memories of last year as the country's biggest online retailer encountered server problems during its Big Billion Days Sale on Monday midnight.

Clearly, spiked traffic on the Flipkart app caused the network glitch, putting a question mark on the retailer's heavily publicised sale yet again. The server glitch irked hundreds of customers, who took to Twitter to express their anger. 

Flipkart's Big Billion Days Sale 2015 is limited to app access only and shoppers will not get discounts on the website. After last year's failed attempt, Flipkart made some arrangements to ensure history does not repeat.

The online retailer set up additional data centers, call centers and offered additional services to employees to deliver a glitch-free shopping experience.

When we tried accessing Flipkart's app late last night, the pages loaded slower than usual and also returned server errors occasionally. We had to wait for a few minutes before trying to shop again. Luckily, it was not a long stretch of outage on the app, but many shoppers are apparently unhappy.

Twitter was stormed with user comments about errors during Flipkart's Big Billion Days Sale. In fact, the hashtag #Flopkart trended on Twitter.

Take a look at a few tweets below:

In competition with Flipkart, Amazon India has also kicked off its Great Indian Festive sale. Both retailers are offering attractive deals.

Snapdeal concluded its big Monday sale on 12 October without causing any outages or server glitches. The Flipkart and Amazon sale runs through 17 October and it remains to be seen how these e-commerce firms handle the traffic.
