SINGAPORE - A major cloud computing network was hit by an outage on Tuesday (June 21), causing many prominent websites and services to go offline for more than an hour.

Content delivery network Cloudflare reported a critical incident at 2.43pm, noting that connectivity had been "disrupted in broad regions".

Chat platform Discord, video-streaming service Crunchyroll and e-commerce platform Shopify were among the services affected.

Some cryptocurrency trading platforms like Coinbase were also affected.

Cloudflare said it had implemented a fix at 3.20pm and was monitoring the results.

DBS Bank was also affected in the outage.

Its mobile app reported “technical difficulties” and some users were unable to log into their accounts at around 2:44pm.

DBS is known to rely on Cloudflare for some of its services, including Web hosting, according to publicly available website registration information.

A DBS spokesman confirmed that digital banking services were impacted on Tuesday but were “restored very quickly”.

In response to queries, Cloudflare told ST the outage was not the result of an attack.

“A network change in some of our data centres caused a portion of our network to be unavailable,” said a spokesman.

Cloudflare added that users may have had difficulty reaching websites and services that rely on its network from approximately 2.28pm to 3.20pm Singapore time.

“Cloudflare was working on a fix within minutes, and the network is running normally now,” the spokesman added.

“Given Cloudflare’s scale and the percentage of the Internet that relies on our network, when we have problems it is vital that we are open and transparent about what happened, why it happened, and what we’re doing to ensure it doesn’t happen again."

The spokesman added that Cloudflare would release a post-mortem on its blog.
