What Caused Facebook and Instagram To Go Down

Unless you have completely stopped using social media, you must have witnessed the recent simultaneous blackout of Instagram, Facebook, and Whatsapp. You would have most likely heard the explanation by the day’s end. But you must have been perplexed by the random tech jargons that were being thrown around by the media reporting the outage. This blog will help explain what exactly happened on October 4th.

The Background

Facebook is a huge organization. It has thousands of servers and other equipment that make it possible for everyone across the globe to access its website. Facebook has to create an internal network to link all its machines to the internet. Just like we have to set up a router and modem in our homes to connect to the internet. Facebook has nearly 3 billion global users. So they use a fiber optic cable that circumnavigates the globe to be able to provide service to such a huge number of users. Facebook refers to this internal network as a backbone network.

Facebook’s backbone network is not directly connected to the internet. It has to pass through two networks before it can be accessed by any external user. These two networks are Domain Name Server (DNS) and Border Gateway Protocol (BGP).

What is the Importance of BGP and DNS?

When a website goes down, it is often linked to DNS. So what exactly is DNS? It is a simple premise. If you want to access a website, a physical computer must send a signal to the computer you are using. Imagine the internet as an upgraded super-fast type of conventional mail. If a friend owns a website you wish to access, you will write them a letter requesting that website. Your friend will reply back by sending you the requested website.

However, you need to know the receiver’s address before writing a letter. Your computer also needs to know which other computer it needs to talk to before you are able to access your desired website. Initially, it doesn’t have this information. The only thing it is aware of is the name of the website you are trying to access. So then your computer connects to a DNS computer via your internet router. DNS converts domains (like google.com) into addresses. The DNS server locates websites through IP addresses. DNS computers maintain domain lists. They also have their corresponding IP addresses. Sometimes your DNS might have no idea where to look for a website. When this happens, it will communicate to another DNS that will know where to search for the requested website.

Facebook uses some internal networks to run its operations. They call it a backbone network. Facebook is a private network. So it doesn’t want other people’s DNS to know all of its own IP addresses. To solve this problem, Facebook uses its own DNS, which determines where to route access requests. This is a standard operating procedure for all medium to large tech firms.

However, DNS alone is not enough to manage operations for Facebook because of its large number of users. Facebook employs an additional protocol known as Border Gateway Protocol (BGP). Earlier, we discussed how DNS determines the addresses of computers to which you wish to connect? Once a letter is written, packed and addressed, and sent to a mailbox, you need someone to figure out how to get the letter from its origin to its destination. BGP does these logistics operations on the internet. It computes the optimum path and conveys that information to your computer when you are trying to access a website.

Most businesses do not either have enough resources to afford BGP servers or their websites generate small enough traffic to not require the use of a BGP server. Typically, only ISPs and large technology firms like Facebook or eBay use BGP servers.

So, What Exactly Happened?

While conducting a regular maintenance check, an engineer inadvertently shut down the backbone network of Facebook. All the numerous computers and servers used by Facebook were still running. However, their connection with each other had been severed.

Without access to the backbone network, Facebook’s DNS was unable to trace IP addresses back to its computers. The DNS servers simply relayed this information to the BGP servers.

The BGP computers were then forced to deny authorization to anyone wishing to access Facebook’s website. For Facebook users, all paths leading to the website were blocked and we were therefore unable to visit facebook.com.

Summing Up

Facebook, Whatsapp, and Instagram have emerged as the holy trinity of the internet over the past several years now. It must have been extremely frustrating to experience such a massive blackout of these vital platforms. We all desire to have a reliable internet connection that provides instant and secure access to every website and app in the world. Spectrum ensures you get that reliability. Their customer support is always eager to assist. You can even request support in Spanish by dialing Numero de Spectrum.

Why do I have a Random Stinging Pain in my Eye?

Published

on

4 Signs That Show It's Time To See A Dentist

Stinging pain in the eye can be a symptom of several different conditions, depending on the type and severity of the pain.

This pain can affect one or both eyes. Reasons for this pain include several conditions and factors, including injuries to the eye, bacterial or viral infections, and irritation from environmental causes.

Certain eye pain can indicate conditions that are easy to treat after being picked up during an eye exam, while others may be more serious and require immediate attention.

Feeling a stinging pain in the eyes, sharp pain in your eye—which is described as stabbing pain, burning, or shooting pain—isn’t just uncomfortable; it’s unsettling. We can find out a range of different causes for this type of eye pain, from easy to manage to others that are more serious. Understanding the symptoms and signs is important to decide whether you need to visit your healthcare provider or emergency medical treatment.

1-Dry Eye

 Dry eye syndrome indicates a disorder in which the eyes cannot create enough tears to keep the eye wet. Dry eyes can cause light sensitivity and headaches, which can cause discomfort behind the eyes.

2-Foreign Body in the Eye

When something drops in your eye and your body’s normal flushing system—blinking and tears—doesn’t work, you may experience a quick, acute pain in your eye.

3-Cluster Headaches

Cluster headaches are the pains on one side of your head and may include tearing of the eyes, a droopy eyelid, and sharp pain, as well as burning or ongoing stabbing pain.

Corneal abrasion. It is a scratched cornea. Although most corneal abrasions are not serious, they can be very uncomfortable and cause light sensitivity and watery eyes.

4-Optic Neuritis

Just as puffiness around the eye due to an infection can contribute to discomfort, an infection or inflammation in the optic nerve can, too. It indicates optic neuritis (a serious eye condition that mandates a visit to the optometrist’s office). In addition to the uncomfortable feeling behind your eye, you might experience these symptoms: a blurry field of view, darkened vision, and trouble seeing color saturation.

5-Infections

Any kind of infection of the eye is often viral or bacterial. These infections, if not treated, can progress in severity. An eye injury or sometimes from unhygienic contact lenses could lead to such issues. Sinusitis, which is not an eye infection, can cause a pressure sensation behind the eyes making the entire area achy and tender. These neglected infections can worsen and spread to common areas leading to further complications.

6-Glaucoma

One of the most common types of glaucoma, open-angle glaucoma, does not cause pain in most cases. But the sudden pressure change in acute-angle-closure glaucoma, sometimes called narrow-angle glaucoma, can cause severe pain, nausea and vomiting, redness, and blurred vision.

When to See a Doctor

Severe or persistent eye pain can indicate an underlying medical condition, such as uveitis, scleritis, or angle-closure glaucoma.

you should visit an eye specialist if you experience the following: A person should contact an ophthalmologist or their regular doctor if they have:

  • Stinging eye pain
  • eye pain that does not go away after a few hours
  • visual disturbances, such as blurred vision or dark spots
  • visible swelling of the eye or nearby tissues
  • nausea or vomiting

How is Eye Stinging Treated?

Most of the time, the issue of stinging pain in the eye is treated by determining the cause of the pain and then treating that cause. Generally, there is no need for pain medicines.

For infectious conditions, the treatments include:

  • Eye drops that decrease inflammation (corticosteroids) or enlarge the pupil to reduce discomfort and edema.
  • Antibiotic, antifungal, or antiviral eye drops.
  • Non-narcotic drugs are taken orally to alleviate pain or allergy symptoms.
  • Lubricating eye drops.
  • Surgical procedures can use transplanted cells or a whole cornea to replace a damaged or scarred cornea. Surgery can also be used to restore eye muscle function or remove a foreign item from the eye.
  • Laser surgery can improve drainage in the eye in cases of glaucoma.
  • Prism glasses or eye patches are useful to assist in recovery from certain conditions such as microvascular cranial nerve palsy.

Conclusion

You should contact an eye doctor if you experience severe eye pain or any eye pain that lasts for more than a few hours, as these symptoms can indicate a more serious underlying condition.

Frequently Asked Questions(FAQs)
