Update Google allowed one of its Gmail SSL certificates to expire days after promising users improved webmail security.
Because Google's certificate for IMAP/POP traffic expired on Tuesday users were confronted by a potentially confusing "invalid certificate" warning. In some cases users may also have been left unable to send email. Google fixed the problem within hours on Tuesday afternoon (US time).
Forgetting to renew a digital certificate can happen to any organisation, as Microsoft and HSBC (among many others) are able to testify. Even though a certificate is out of date a secure connection with a site can still be established. Google makes it its business to index all the world's data so its own failure to manage a key domain is an embarrassing faux pas even though no harm, or much inconvenience, was caused.
Reg reader Peter Houppermans, who brought the slip-up to our attention, drily notes that users are now so well trained to blithely click on past invalid certificates, so that this sort of thing should present no great problem. ®
