National Stock Exchange or NSE servers were down, stopping all kinds of trading, as people reported that the rates aren¡¯t updating. Moreover, NSE has gone ahead and halted all trading from 11:40 AM IST.
The aforementioned stock exchange has also revealed in a statement on the microblogging platform Twitter that they are facing issues with their telecom service providers.
¡°NSE has multiple telecom links with two service providers to ensure redundancy. We have received communication from both the telecom service providers that there are issues with their links due to which there is an impact on NSE system.¡±
It added, ¡°We are working on restoring the systems as soon as possible. In view of the above, all the segments have been closed at 11:40 and will be restored as soon as the issue is resolved.¡±
As of now, this has only impacted NSE as S&P BSE Senex is still showcasing live price quotes. What has been affected are the updating of 11 Nifty sectoral indices due to the aforementioned glitch.
What¡¯s saddening is that this happened on a day when the market started on a very positive note with Sensex going over 200 points, while Nifty remained over 14,700 points. Reports have hinted that the services will start again at 1:00PM IST.?
Of course, people on Twitter took no time to react.?
Crashes on a massive level are rare, but when they do occur they take everything down while causing catastrophic damage along the way. Just like NSE¡¯s crash, here are some of the major crashes in history that made the lives of people hell, for a brief period.?
This crash affected individuals across two continents -- the United States and Europe, while affecting the functioning of popular platforms such as Airbnb, Amazon, BBC, CNN, eBay, Netflix, and Twitter. Multiple DDoS attacks targeted systems under Managed Domain Name Systems (DNS) service provider Dyn.?
It is regarded as one of the largest DDoS attacks in history. The attack originated from malware vulnerabilities in a large number of internet-connected devices like printers, IP cameras etc. This forced several websites to take their operations offline, costing them millions in revenue.?
In 2017, a massive IT crash on a global level resulted in the entire fleet being grounded, affecting travel plans of thousands of passengers not just in the UK, but around the world who were planning to board a British Airways flight.?
What caused this IT failure was something rather hilarious -- An IT maintenance contractor accidentally switched off an ¡®uninterruptible power supply at one of the data centres that destroyed the server with the power surge.??
2017 was home to another massive server crash, this time by Amazon Web Services or AWS. This occurred after Amazon¡¯s S3 web storage service started experiencing crazy error rates that caused partial or full outages for several websites including publications like Business Insider, even Quora and Slack and its users around the world. This originated in AWS¡¯s US-East-1 data centre.?
2020 -- the year we dread to even think about -- stayed true to its nature till its very end. In December 2020, we saw Google services crash, causing a global outage of popular services like YouTube, Gmail, Google Drive, Google Meet and others -- all this when several people were working from home during the pandemic.?
An investigation later revealed that this was caused due to an internal storage quota issue. Basically, the system that would allocate storage for each of Google¡¯s services malfunctioned, reaching the threshold of its storage capacity. The blackout lasted for a good 45 minutes before everything was back online.?
In 2019, we saw the world get disconnected from Wikipedia sites for a whole nine hours. The cause was a massive DDoS attack. In case you didn¡¯t know, a DDoS attack can cause immense strain on the web infrastructure of the target while also congesting networks, resulting in severe packet loss. The site saw a packet loss of up to 60 percent from several nations across the world.?
