Everyone who has been trying to access facebook and instagram are not able to get through for about 35+ minutes today!. It seems their DNS servers are not pointing to the servers or they are under DDOS or may be they are upgrading??

The ping, trace route and HTTP request lookups are all returning null/false. Verified from India, USA, HongKong, Sri Lanka…

No news why it is down yet!

Their WhatsApp service is still working though!

Facebook has been down for short intervals all around Jan 15, but never for this long…

Awaiting an official update from facebook.



Facebook later explained that the site outage was due to some work they were doing on the site’s DNS servers. Early this morning, the engineers have made a change to the DNS infrastructure and that lead to the temporary unavailability for the users!

In fact, the major problem which is the cause to this outage is the users itself. Yes, you read it right!

Every attempt of the user to access Facebook resulted in a query which in turn interpreted as an invalid value, further, deleting the corresponding cache key. This meant that even after the original problem had been fixed, the stream of queries continued. As long as the databases failed to service some of the requests, they were causing even more requests to themselves. We had entered a feedback loop that didn’t allow the databases to recover, stated by the Facebook engineer!

In the past:

Sources tell us that to sort out this problem, they had to shut down the server for a while and fixed the root cause of this problem. The Facebook engineers have even turned off the automated system that attempts to correct the configuration values and exploring the configuration design patterns at other systems at Facebook.

Good for Twitter?

Twitter has been getting a lot of traffic ever since Facebook has been down

My Point of View:

They might be trying something new and ended up having some serious issue with the automated load balancing and user management system.


It is back! = @ 12:39:20 PM IST
