As a user of ChemSpider you may have noticed of late the persistence of an increasing number of timeouts following searches. The issue has been traced down and resolved, we hope. However, it appears that this issue had persisted for a “while” but it was only recently brought to our attention. There is an ongoing increase in ChemSpider usage and as the load on the servers increases the system is starting to respond, sometimes inappropriately. In order to optimize performance based on load we need YOUR feedback when you see either performance issues or simply bugs or behaviors which don’t make sense.

Please don’t assume that someone else will report a behavior you observe. Let us know directly by sending an email to (represented this way for the purpose of anti-spam). You will find us very responsive and willing to help. Thanks
