Amazon Web Services (AWS) has fixed a capacity issue affecting one of its instances, which had prevented users from using a particular service on Friday.
The capacity issue affected t2.micro instances, but the company insists that its London data centres, which only opened in December last year, are not suffering from capacity issues.
According to sources who contacted V3, attempts to expand their usage in the EU-West-2a zone had been rebuffed due to capacity issues: "We currently do not have sufficient t2.micro capacity in the Availability Zone you requested (eu-west-2a)."
In response, AWS admitted that there were problems with provisioning for the t2.micro instance capacity, but insisted that its London data centres weren't running short of capacity.
It later updated its service status to reflect complaints, following questions from V3: "We are temporarily running low on t2.micro instance capacity in the EU-WEST-2 Region. All other instance types are available.
"For customers that do receive an Insufficient Capacity Error for an instance launch request, we recommend using t2.nano, t2.small, t2.medium, t2.large or any of the other instance families.
"We are working to increase t2.micro instance capacity and expect to be back to normal levels within the next few hours. Instances that are currently running are not affected."
And the company claims that it fixed the problem by 7pm on Friday.
The teething issues come weeks after AWS customers endured a US east coast data centre outage as a result of a technician's typo at the end of February.
Amazon's London data centres have only been open for four months - the third in Europe after Ireland and Frankfurt. The facilities are leased from third-party providers.
In addition to demand from financial services organisations in London, AWS's UK data centres will have attracted the interest of organisations seeking to cover themselves should the replacement for Safe Harbour, dubbed Privacy Shield, be struck down by the European Court of Justice.
On top of that, they also need to prepare for the EU's General Data Protection Regulation (GDPR), which will require organisations to disclose security breaches and give the ICO the power to levy fines of up to four per cent of an organisation's turnover.
