Lets encrypt is reliable from our point of view - never had an issue with it - we occasionally have issues when renewing certs - we have about 90 of them - but that is mainly with the "fake-manual" process of updating DNS which is not 100% reliable with the changes we make. In use speed should be no different from any other cert - as long as you have the appropriate intermediates and your browser has the right root certs. You can also create a cert with multiple SANs so you may only need one cert anyway. -- The Wellcome Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
