Resolved

We have not seen the bots back again so we're closing this while all the services have been fine for over 24 hours.

Monitoring

The bots hitting our API have either been blocked or backed off, so we're monitoring closely. So sorry for the break in access.

Investigating

We are currently trying to identify and block the bots that are hammering the API. Metadata Search and Content Negotiation are also affected. We'll update here soon. In the meantime, if you're an API user, please try the 'polite' pool i.e. include email identification in header requests.
