To enable as many users as possible to access our services, please note the following:
HTTP-related service (website and REST API)
- More than 500 UDL requests (HTTP GET) on the website in less than 6 minutes: access denied for 24 hours (renewed for each UDL request)
- More than 666 HTTP requests in the last minute: access denied as considered DOS/bad bot for 5 minutes
- Too many unfollowed HTTP redirect requests (approx. 100) in the last 10 minutes, with a check every minute: access denied as considered DOS/bad bot for 15 minutes.
Any downloads of daily/monthly XML packages from the website are counted in the HTTP-related service.
There is a restriction on the maximum number of connections:
- Maximum number of overall connections approx.1,050, but this number can be decreased to approx. 525 if the server is under maintenance
- Maximum of 3 concurrent connections by IP or user
- Maximum of 100 concurrent connections for ‘legacy’ users (i.e. not guest accounts) as same account could be used by several IPs.
For the FTP service, once the limit is reached, the server will refuse new connections from the IP/user. Once the connection is released, a new one will be accepted.
TED Notice Viewer API
The TED Notice Viewer API service is also meant to be on demand and not used excessively.
Recommended usage is limited to 50,000 calls to the API per month outside of the peak concurrent user timeframe (before 8.45, after 14.00 CET):
- Maximum of 1 concurrent request by IP, with no limit on the total number of requests.
Contact form usage
Sending more than 4 requests through the TED contact form over a 1-day period means that you cannot access the full system for 10 minutes.
