Cloudflare and the responsible network for the route leak have now fixed the issue. Connectivity should now be recovering. We will continue to monitor the effects on the cdnjs services and follow updates from Cloudflare.
We have been made aware of some users who are having connectivity issues to both our main website and the CDN service. We believe at this time that this is due to network issues that Cloudflare are experiencing. This is likely to also impact our API, though we have no reports of this yet.
