We are planning to upgrade our portal software to MetaLib version 4.3.
Unfortunately, a downtime of several hours will be inevitable, consequently vLib is likely to be unavailable between 08:00 and 12:00 a.m. that day.
We would like to apologize in advance for any inconvenience.
UPDATE (16 September, 12:19): Installation process delayed. Services continue to be unavailable.
UPDATE (16 September, 15:45): Services available again.
