E-mail service is down

Tuesday, November 2nd, 2021

O serviço de e-mail está indisponível desde as 00h05 de hoje, dia 2 de Novembro de 2021.

A causa do problema está relacionada com uma corrupção de dados do sistema de armazenamento, que afectou milhares de caixas de correio. Apesar do múltiplos níveis de redundância que a solução de mail possui, a recuperação de dados implicará a utilização do backup das últimas 24h. A equipa está a trabalhar para repor o serviço de e-mail o mais depressa possível.

Nesta fase ainda não é possível saber que quantidade de e-mails das últimas 24h é que poderão ter sido perdidos.

Pedimos desculpa pelo transtorno causado.
