Perseus Digital Library

Perseus 4.0 Outage

As of April 7, 2026, malicious traffic has interrupted service on Perseus 4.0 and related sites.

The Scaife Viewer remains online at this writing.

We will update when we have further information

As many of our users are aware and have reported, the Scaife Viewer (https://scaife.perseus.org/) text search has been down for several months. The problem was first documented in late November, and we apologize for any inconvenience and frustration this may have caused.

We are currently in the midst of a developer transition that has limited our ability to fully investigate and resolve this issue. Development work is also currently engaged in implementing and beta-testing the rollout of vocabulary tools within the Scaife viewer, a feature long requested by many.

We are aware of the problem this creates with making full use of the Scaife viewer and are actively working to resolve it as quickly as possible. We thank you for your patience.

Scaife Viewer | Home The Scaife Viewer is a reading environment for pre-modern text collections in both their original languages and in translation. It is the first phase of work towards the next version of the Perseus Digital Library, Perseus 5.0.

The Perseus servers are currently being flooded with requests from overseas servers. The systems administrators are endeavoring to block the bad actors and maintain operations, but there may be disruptions until all of the relevant domains can be identified. We thank you for your patience.
