When trying to search in the METLIN database, I'm always encountered with the message "You don't have permission to access / on this server". But the isoMETLIN is accessible. Is it also the case for others?
yes, so do I
METLIN is running fine however certain regions have been attacking the site so we have had to restrict access to those places until the attacks stop.
What does this mean "We have detected abnormal behavior from this IP address/User ID, and have temporarily blocked access for some period of time. Access to this page will resume shortly."..?
