The late Monday and early Tuesday outage at internet infrastructure provider Cloudflare affected a large number of websites, including Peloton, Fitbit, DoorDash, Discord, and NordVPN, according to Downdetector.

People attempting to access Cloudflare-protected websites were greeted with an Error 500 message in their browser - a generic server reply when unexpected conditions occur, indicating that the server is unable to fulfill a request.

The company's status page has been regularly updated, with the most latest update confirming that the first fix it implemented was successful and that all systems are now operational.

According to DownDetector, a crowdsourced web monitoring tool that tracks outages, the internet infrastructure firm fixed the situation less than 2 hours after users had problems accessing several sites, such as messaging platform Discord, Shopify, and Coinbase.

Users in the United Kingdom appear to have been largely unaffected, as many of the allegedly affected sites were accessible to users in the region during the outage.

According to The Verge, users of Cloudflare's DNS lookup service were among the most affected, but resetting to the internet service provider's default configuration mostly fixed the problem.

Given the modern internet's centralized model, disruptive outages like these are relatively common.

According to some experts, the majority of the world's websites are proxied by a small number of content delivery network (CDN) providers, the most popular of which are Cloudflare and Fastly. CDN providers provide a service that speeds up the delivery of internet content such as web pages.

After the company's website was affected by Cloudflare's service issues, the CEO of OKX, which has seen $1.47 billion in trading volume in the last 24 hours, tweeted asking for a "web3 alternative in the future."

FTX, the world's second-largest cryptocurrency exchange, briefly went into "post-only" trading mode when it became inaccessible during the outage, according to a tweet from the company. The mode ensures that an order is placed only if it is placed by a "maker," or someone who sets a price to buy or sell.

Etherscan, a block explorer, and Bitfinex, a cryptocurrency exchange, both tweeted that their websites were unavailable. Many of the services affected by the Cloudflare outage were restored within two hours.

Reports of Cloudflare issues began around 11:30 p.m. PT Monday, and the company reported that the problem had been resolved shortly after 1 a.m. Tuesday, PT

The company stated in an emailed statement that the outage was not the result of an attack.
