Why Cloudflare outage broke swathes of the internet?

Cloudflare is experiencing problems, causing widespread disruption to online services and platforms.

Why Web domains and Apps failed to connect

Cloudflare experienced an outage on Tuesday morning, according to its status page. Cloudflare’s technology powers numerous other sites and services across the internet, and the outage seemed to impact a range of different sites, including Discord, Shopify, Grindr, Fitbit, and Peleton, according to Downdetector. Reports of issues started at around 2:30AM ET. Cloudflare reported that it resolved the issue at 4:06AM ET.

Cloudflare fixes outage that knocked popular services offline

The issues were most problematic for users of Cloudflare’s own DNS lookup service.
Multiple Verge staff members found they were unable to access any websites at all during the outage as a result of using Cloudflare’s 1.1.1.1 DNS service. Thankfully, the fix here is simple: change your DNS configuration. I found that simply switching back to using my ISP’s default DNS settings resolved most of my issues.

Cloudflare said on Tuesday it resolved a “wide-spread” outage earlier in the day that affected a large number of services including FTX, Discord, Omegle, DoorDash, Crunchyroll, NordVPN and Feedly. The internet infrastructure firm resolved the issue roughly an hour after users began facing issues accessing some popular sites including Zerodha, Medium.com, news outlet Register, Groww, Buffer, iSpirt, Upstox and Social Blade.

Cloudflare is one of today’s major content delivery networks (CDNs).

The US firm also provides distributed denial-of-service protection to online domains, speed optimization, and various cybersecurity services.

The company accounts for millions of customers worldwide, including major enterprise firms.

a number of websites and online services suddenly went down, including Feedly, Cloudflare itself, blogs, cryptocurrency services, and more. Ironically, this also meant that down detectors – websites used to check the status of another domain you are having trouble connecting to – also went offline.

Users had also indicated that they were struggling to use Coinbase, Shopify, and League of Legends, according to DownDetector, a crowdsourced web monitoring tool that tracks outages.

Cloudflare, Inc. is an American content delivery network and DDoS mitigation company, founded in 2010.

It primarily acts as a reverse proxy between a website’s visitor and the Cloudflare customer’s hosting provider. Its headquarters are in San Francisco, California.
