They have stated they had issues with link to DB server hence the proposed hardware maintenance to resolve the random lag values, but it has not been resolved 'fully' AFAIK.

As we have announced yesterday on October 10th, we had made server maintenance that was aimed at fixing the issues we had with our database which was causing it to lag (occasionally) for up to 10~15 minutes at a time (causing the site to be down for that duration).
"Due to more frequent issues with our database, and as the 10Gbps adapter on our old server started having problems (random packet loss, etc), we deemed it necessary to implement the new infrastructure and organized this emergency maintenance."
