Cloudflare experienced a service interruption in the early hours of Dec. 5, causing access issues across numerous crypto platforms.
Centralized exchanges such as Coinbase and Kraken, as well as the user interfaces of several decentralized finance (DeFi) protocols, were unreachable for parts of the morning.
This issue is now resolved. Thank you for your patience.

Coinbase soon updated that the issue was resolved and the platform was working well.
Cloudflare said it is investigating as its systems stabilize.
Internet users also reported seeing error messages when attempting to load sites tied to Cloudflare services, including outage-tracking platform Downdetector.
Cloudflare outage appears during scheduled maintenance
At the time of disruption, Cloudflare was also conducting its scheduled maintenance checks in its Bogota, Detroit, and Chicago data centres.
The company said users in the affected area may notice slightly slower performance while maintenance is underway.
It also told customers who connect through PNI/CNI at that location to expect their traffic to switch to other routes, because some network interfaces in that data center might be temporarily unavailable during the maintenance period.

The disruption follows a similar incident on Nov. 18, when Cloudflare reported an “internal service degradation” that affected platforms including BitMEX and DeFiLlama. At the time, the company said it was working to restore impacted services.
As with the November incident, a large number of crypto users found themselves unable to access X as well as platforms such as Coinbase and Kraken.
