New limitation on SIMBAD queries : you should not query more than 6 queries per second from the same @IP, otherwise the IP is blacklisted during 1 minute.

We experimented too many queries than the server could handle, so we

had to add a limitation.

You should not query more than 6 queries per second from the same @IP,

otherwise the IP is blacklisted during 1 minute.

Please send less queries in parallel, or add timing between queries.

I hope to be able to relax these limitations in the future.

If you experiment some problem, send us an email
