Today HYIP-field, an official blog of LibertyReserve, announced scheduled work on 29 May, 8:00 GMT. At this time the site of Liberty Reserve will be unavailable. Anyway you won't be able to make payments for two hours.
Some investors usually start panic in such cases, yet this practice is common. We can't say for sure how much will this downtime affect the HYIP-players, yet it won't probably be serious. According to the program's admin this upgrade will give you a faster, more productive system.
