Like many other sites nowadays, FairMarket uses Let's Encrypt for it's SSL certificates, which provide secure use of the site. On St Valentine's morning, 14th February, quite a few users reported the site was inaccessible and they were faced with a big scary error page. This message is just to let people know that the certificate had expired, so nothing else was actually wrong with the site. It was renewed pretty soon after it was reported and we trust it will now be able to be renewed automatically. A big thanks to all those who quickly reported it!
