On Tuesday some users of password management site LastPass had difficulty signing into accounts following an outage at one of the data centers the company relies on.

In a company blog post LastPass CEO Joe Siegrist said at 3.57am ET the company took action to migrate LastPass to run at another facility.

A number of ISPs (Internet Service Providers) experienced technical problems on Tuesday that resulted in poor service throughout the US and some parts of Canada according to ZDNet.

Service provider Level 3 released the following statement: "Our network is currently experiencing limited service disruptions affecting some of our customers. Ensuring the stability of our network and communications services is our primary concern and we are dedicated to minimizing impact to our customers. Our technicians are currently working to restore services as quickly as possible, and we are in close contact with affected customers.”

ZDNet said although ISP maintenance activity may have contributed, the real problem was that Border Gateway Protocol (BGP) routing tables have grown too large for some top-level Internet routers to handle – meaning the routers could no longer handle Internet traffic.

Web hosting company LiquidWeb also experienced a problem when its whole website came down.

Users experienced connection errors to the LastPass website and its services, with most unavailable throughout the morning.

Siegrist said the majority of users were unaffected due to LastPass having ‘proper redundancy’ in place to deal with a data center outage.

By 5am LastPass made the decision to migrate to another data center, bringing its data center connections from two down to one.

Siegrist stated by 9.30am latency and connectivity issues increased at the only online facility.

“12:00 pm - We tracked down the source of an issue at the second data center, in which three machines we had added were running at 100Mbps instead of Gigabit (despite having Gigabit cards and being connected to Gigabit switches) and were network saturated,” Siegrist wrote in the blog.

LastPass announced by 8.45pm ET it had completed testing and confirmed that replication to its secondary data center looked good, and it was fully restored with both data centers active again.
