Today access to Strava.com and uploads from our mobile applications were affected by a distributed denial of service (DDoS) attack on the service that hosted our DNS – GoDaddy.com. Our web site and services are hosted by Amazon Web Services, but our DNS was not. When GoDaddy was attacked we immediately began migrating our DNS to another provider. Strava.com, as well as our Strava Run and Strava Cycling apps for iPhone and Android, are already working again for many, but it may take up to 48 hours for all the new settings to take effect for everyone.
We apologize for any inconvenience that this down time may have caused you. Uploads from your Garmin devices and mobile phones should now work although some few may still experience delays.
Thanks for your patience!
